Hello everyone, we have started to use a new Schneider PLC M238 and we have some problems with Modbus communication. We are reading holding registers (%MW49=400050) and writing to this modbus register. This work's OK. Now we need to write a coil. On the M340 this was done like this: %M100= modbus register 000101.

Hi, I am going to use xCP Modbus slave driver for CP340 http://www.runmode.com/xcp_modbus.html. Now I have another problem.

Hello everyone! I have just recived a CPU S7-313C with DI/DO modules, CP340 communication card and MD720-3 gprs modem. This is a water plant wich I need to put into scada iFix. I have a few experience with simatic plc but not very much with communication protocols with S7. I know this CP340 card does not support modbus protocol (driver). What protocol does this card support so I can linked to iFix scada. Is this SI7 or something else and how do I do it? Best regards

Thank you for the answer

Hello! Has anyone connect TWIDO plc trough GSM modem with a modbus OPC server on PC. How to configure in programme twido so it will call the modem connected to PC where is an OPC server installed? Any example would be a big help! Thank you

The twido port 1 is set to Modbus and not to Remote link. And yes I have PIN5 and PIN7 on the MINIDIN together and connected to COM on the coverter from the start. I think Henrique is wright. Twido has a limitation in comm. packet.

Hello! I am trying to communicate with TWIDO TWDLCAA10DRF trough modbus OPC server. The server doesen´t poll the data from TWIDO. If I poll the same data with modscan, it work´s OK. Are there any additional settings to make in the Twdio so it will communicate with opc server? This standard modbus OPC server communicate´s fine with any other PLC´s. Have a nice day

I don´t know what else to try. Please help.

I am using Mb1 opc server from geFanuc for modbus serial communication. My communication parameters are 9600,8,1,N (RTU) and Twido has modbus address 2. I am reading registers 400001 to 400008. I am using a coverter from RS485 to RS232, because Twido has RS485 port. If I connect Modicon momentum to this OPC server it work´s OK. What am I doing wrong?

I think the cable is OK. The dialog table on the XBTH is configured. What do I have to configure on the Twido PLC? Do you mean with the EXCH function? Best regards

OK, thank you for the information! I want to lock the program with password, so that when someone want´s to change it or upload it from the PLC has to know some kind of password. Is this possible and how can I do that? Have a nice day

Hello! We have a problem with adding DI to digital registers. Is it possible to add all DI (I0.1.0 - I0.1.64) to digital registers (%M0-%M63) at once and not one by one? This I mean if there is a block to do this? Have a nice day Marjan

Thank you! Now I have another question. I want to put more rows in my FDB sections, but it seems it doesen´t wor, when I change it in the project settings. How can I do that? I was using direct adresses until now (like %M2001,...), but now I want´t to use symbols instead of direct adress. Why doesen´t change in the program from %M2001 to Pump1 when I put the symbol in the variable table with this address? Have a nice day

Now we have another problem. We have erased everything on the PLC (flash, ram,...) but now we can´t connect to it with the default settings or any settings (baudrate,...). Why is that?

Hello again! We have a problem with our Momentum PLC. When downloading the program we get an error LSP SERVICE ON PLC FAILED : ERROR ID OLL21710 and the error below HEAP SIZE 220 What could this mean? We have the 171 CCC 760 10-IEC modul. Please help

If we download the small version of program it goes OK, but if we try to download the whole program we have problems. Is it possible the program is too big (too much IEC blocks)?

Hello! How can I upload my program from the modicon momentum PLC proper. I have connected to PLC then in the Concept 2.6 Online/Upload. It was uploading something but it didn`t upload anything; the program was still not equal. How do I upload the whole program properly? Please help
