Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>

Post by pascaljt on Function block for Ethernet/IP ^{CODESYS Forge talk (Post)}
Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)
