I have a cb1241 communicating to a 3rd party device via modscan rtu It is working on modscan using adam converter (great job) I see the data when using modscan but am getting nothing on the data block in the PLC when I try that. I have copied the address, incremented it decremented it tried different lengths on data pointer. TO-TO, swapped the AB cables (that did work better as it was stuck on constant busy all the time) the mb_comm_load is reaching done, connection seems ok. The Mb_Master is flashing busy as the clock pulses so also seems ok. I would of thought the address should of been the same with modscan and PLC but alas not. What should I be checking? In modscan the address is holding register 12556, so Siemens address 412556 or 412557? Images on the attachment. AttachmentModBusComms.zip (65 Downloads) |
