Hi all, I need help with WB-MIO and two WBIO-DI-WD-14 modules. I have the WB-MIO connected to Allen-Bradley PLC using MODBUS-RTU, the status LED blink fine with no issues, I have communication, but when I read the Module 1 and Module 2 Inputs registers I don’t get anything. Can someone help me? I…

Let’s check the MIO configuration to work with input modules. Check that the following registers have values. Address (base address for first WD-14 module) - value 11000 - 0xffff 11001 - 0x0000 11002 - 0xffff 11003 - 0x0000 11004 - 0x0000 11005 - 0x4444 10999 - 0x0001 For second module addr…

Good day! I connect MIO to RS-485 port: try recieve modute 1 inputs, WD-14 Define variabe^ export DEV_PORT=/dev/ttyRS485-2 export DEV_ADDR=157 Make Modbus RTU requiest (all inputs open): modbus_client --debug -mrtu -pnone -s2 $DEV_PORT -a$DEV_ADDR -t0x01 -r1000 -c14 Opening /dev/ttyRS485-2 at …

I believe the issue is related to the configuration at WB-MIO. I did a factory reset, but before I can get information at Module 2, but not Module 1. I swap the modules I can only get information at Module 2, using the registers 2000 > 2014, but never from 1000 > 1014. After the factory reset, I c…

Which values should I get at those registers? [image]

I upload again the MIO stable firmware: http://fw-releases.wirenboard.com/?prefix=fw/by-version/WB-MIO/stable/1.5.1/ The same issue, I can communicate, but no information from Registers 1000 > 1014 / 2000 > 2014.

Hello all, I can get again information from Module B (Position 2), but not from Module A( Position 1): [image] The communication between AB PLC and WB has an offset of +1 for the registers ID. I can get the value 256(Input 9 connected between iGND). If I do the same for Module A (Position 1), c…

[image] Sergio_Santos: Which values should I get at those registers? [image] No, for WD-14 not need any configurations, is work with default. [image] Sergio_Santos: Module A (Position 1), change the Register Address to 1001 I don’t get anything: [image] So, let’s check if the firs…

I don’t have nothing from 1250 > 1265. (see the picture) [image] About the “Coil” and “Holding” registers I use a different command for each type. You can see in the picture the translate table by code. Yes, I can get “2” at 997(Module1) and 996(Module 2). [image] [image] With this PLC the …

[image] Sergio_Santos: Do you have any application I can use at Windows with a USB > RS485 adapter? https://www.modbustools.com/download.html Use screуnshot from wiki for correct setting.

OK, thanks. I will do some tests and give more feedback.
