The only thing is that you have to change the Send/Rcv blocks from FB7/FB8 to FB2/FB3. Please find the attachment for the library blocks of the 1SI. If you want any sample program of CP 341, just send one mail to me and I will send the Sample program. Attachment 1Si Modbus Blocks1_V122.zip (395 Downloads)
