ABB 086370-001 Product Overview

In industrial control systems,communication interface modules are the”data movers,”and the ABB 086370-001 is truly an efficient”data mover”!Designed specifically for ABB’s AC 500 PLC and AC 800M DCS,its core function is to transmit field data(such as temperature and pressure)collected by the PLC to the host computer,and then send control commands from the host computer to the PLC,ensuring smooth information flow throughout the system and preventing control failures due to data disconnection.

Don’t underestimate communication modules;the ABB 086370-001 is far more powerful!It supports dual Ethernet and RS485 interfaces.Nearby equipment in the workshop uses Ethernet(fast)for transmission,while more distant equipment uses RS485(longer-range)for transmission,eliminating the need for two modules.A chemical plant previously used a standard single-interface module,requiring converters for remote equipment.This resulted in frequent data loss.After switching to the ABB 086370-001,data loss has remained stable for six months.It also offers strong interference immunity,ensuring rock-solid data transmission even when adjacent to a 100kW inverter.This stability is unmatched by any other module,leading many established plants to specifically request the ABB 086370-001 when upgrading their PLC communication systems.Main Features and Advantages

Dual-interface design enables data transmission both near and far.While standard communication modules offer limited Ethernet(limited transmission distance)or RS485(slow transmission speed),the ABB 086370-001 features dual interfaces.Ethernet transmission speeds of 100 Mbps are available for devices within 100 meters(such as workshop control cabinets),allowing for instant data transmission.RS485 transmission speeds of 115,200 bps are available for devices within 1,200 meters(such as plant pumps),ensuring zero packet loss.A brewery using this module previously experienced frequent data interruptions with its remote pumps.After replacing it with this module,the data transmission success rate increased from 95%to 100%,eliminating pump downtime due to data disconnections.

Multi-protocol compatibility ensures device compatibility:It supports both Modbus TCP and Modbus RTU protocols,connecting to ABB’s own AC 500 PLCs as well as third-party PLCs from Siemens and Schneider.No hardware modifications are required;simply configure the protocol in the software.A machinery factory previously had an ABB AC 500 PLC and a third-party host computer.Ordinary modules wouldn’t connect.After switching to the ABB 086370-001,the protocol setup worked in just five minutes,saving a$2,000 engineering commissioning fee.

It’s highly resistant to interference,even in a chaotic workshop:Industrial workshops have numerous motors and inverters,and electromagnetic interference(EMI)can distort data.Ordinary modules often cause errors when transmitting data.The ABB 086370-001 has 6kV lightning protection on its Ethernet port,30V overvoltage protection on its RS485 port,and double shielding.A steel plant uses it to transmit rolling mill data.Previously,the ordinary module was experiencing three errors per day.After switching to this module,there haven’t been any errors in six months,and the data is incredibly accurate.Wide voltage adaptability,no worries about voltage fluctuations:Conventional modules fail below DC 22V,but the ABB 086370-001 can handle DC 21.6-26.4V,so it’s not affected by power fluctuations in the workshop.A food factory previously had an unstable power grid,with voltage frequently dropping to 22V.Conventional modules disconnected twice a day.After replacing this module,data was no longer interrupted due to undervoltage,and production has become much smoother.

Application Areas

Chemical DCS System:”Data Transmission”:A chemical plant’s DCS system collects temperature and pressure data from multiple reactors.The ABB 086370-001’s dual interfaces are perfectly suited for this purpose:Ethernet connects to the central control room host computer and RS485 connects to the plant floor reactor PLCs.After using this interface,a pesticide plant reduced data transmission latency from 50ms to 10ms,enabling the central control room to view reactor status in real time.Data lags no longer cause reactor overheating,saving the plant 50,000 yuan per month.Metallurgical PLC System”Connects Equipment”:The rolling mills and fans at a metallurgical plant are scattered throughout the factory.The ABB 086370-001’s RS485 transmission capacity is 1200 meters,eliminating the need for extended Ethernet cables.A steel plant uses it to connect to a fan PLC 1000 meters away.Previously,conventional modules consistently lost data.After switching to this module,the data success rate increased from 92%to 100%.The fans no longer shut down due to data disconnections,resulting in an additional 300 tons of steel produced per month and an additional 150,000 yuan in revenue.

Food Plant PLC”Controls Equipment”:The food plant’s production line equipment(filling and packaging)is controlled by PLCs.The ABB 086370-001 connects the PLCs to the host computer.A biscuit factory uses it,allowing production line data to be uploaded in real time.Managers can monitor production progress from their offices without having to visit the workshop,and can also adjust parameters remotely.This has increased production efficiency by 10%,resulting in an additional 20,000 boxes of biscuits produced per month and an additional 60,000 yuan in revenue.Sewage Treatment Plant”Status Monitoring”:Pumps and valves in sewage treatment plants are widely distributed.The ABB 086370-001’s RS485 interface connects to remote pump PLCs and Ethernet to the central control room.One sewage treatment plant implemented this interface,enabling real-time monitoring of pump operating data.This prevented sewage overflows caused by undetected pump failures,saving the plant 100,000 yuan in environmental protection fines and reducing the cost of manual inspections.

Selection Guide/Purchasing Recommendations

When choosing the ABB 086370-001,first consider the”System Model.”If you have an ABB AC 500 PLC or AC 800M DCS and need dual interfaces(Ethernet+RS485)for data transmission,this module is perfect.If it’s a PLC from another brand(such as a Siemens S7-300),first confirm that it supports the Modbus protocol;if it does,it’s fine.I’ve had customers use it with an S7-300,and they just set it up for Modbus RTU.If you only need a single interface,the Ethernet 086371-001 or the RS485 086372-001 are more cost-effective.Let’s look at the”communication distance”:If the device is 100m or less from the control room,Ethernet is sufficient.If it’s between 100m and 1200m,RS485 is sufficient.If it’s over 1200m,add a repeater;don’t force data transmission,otherwise data will be lost.A customer previously experienced a 20%packet loss rate when transmitting data over 1500m without a repeater.After adding a repeater,the packet loss rate dropped to 0.1%.

Don’t buy”refurbished”parts!The ABB 086370-001 communication chip and lightning protection circuit are the core components.Refurbished parts use older chips,have poor interference resistance,and are prone to disconnection.A customer once bought a refurbished unit and experienced data loss due to interference after just two months,leading to reactor overheating and a loss of 80,000 yuan.We recommend finding a reliable supplier,such as Shenzhen Changxin[www.cnplcdcs.com].We offer genuine,original products,and each unit has a verifiable serial number,ensuring peace of mind.Frequently Asked Questions(FAQ)

Q:Can the ABB 086370-001 be used with the ABB AC 800M DCS?

A:Absolutely!They are a”natural pairing.”The ABB 086370-001 supports ABB’s proprietary protocol and connects directly to the AC 800M bus without any parameter changes.A chemical plant previously used this configuration and has had no communication issues for two years,with remarkably stable data transmission.

Q:Why do I keep getting data packet loss when connecting the module to an RS485 device?

A:Check the wiring first!RS485 uses a differential signal and requires shielded twisted-pair cable.Do not reverse the A and B wires,and add a 120Ωtermination resistor at the end.If the wiring is good,check the transmission distance.If it exceeds 1200m,add a repeater.If everything else is good,check the baud rate and set it to 9600bps or 19200bps.Don’t set it too high.A customer previously experienced packet loss at 115200bps,so reducing it to 19200 fixed the problem.

Q:How many RS485 devices can the module connect simultaneously?

A:Up to 32!However,be aware of the bus load.Each RS485 device should have a load of≤32Ω,and the total load should not exceed 512Ω,otherwise the signal will be attenuated.A customer previously connected 30 devices without overloading,and the operation was stable.If the number exceeds 32,adding an RS485 hub and splitting the connection into two paths will resolve the issue.Q:Is the module’s Ethernet port lightning-proof?Will it fail in the rain?

A:Yes!Its Ethernet port has 6kV contact discharge protection,which can withstand the voltage induced by ordinary lightning strikes.A factory in southern China experienced lightning strikes on rainy days,damaging other equipment,but the ABB 086370-001 module remained intact and continued to transmit data normally.However,if the module is struck directly by lightning,it will still fail.Therefore,it is best to add lightning protection grounding to the control cabinet for double protection.

Customer Case Study/Successful Application Analysis

A chemical plant in North China previously used a standard single RS485 communication module to connect the reactor PLC and the central control room.They encountered numerous problems:RS485 data transmissions over 1000m often resulted in packet loss,three disconnections per day,and a significant impact on the reactor.
