Post by mattkaree on Mapping values with etherCAT mailbox communication ^{CODESYS Forge talk (Post)}
I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?

no - you need to update, smallest impakt is just to install the debiab package on target side. Nothing else ( no updates in CODESYS)

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 tk096 on Motion FB Error ^{CODESYS Forge talk (Post)}
Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

Have you received any feedback or found any solutions to the load problem. We are running into similar issues, even without codesys running the load avarage is above 1 meaning that it is to busy already without plc code running. Hope you might have some more insight.

I dont know exactly why this error happens, but I think its because you have some wrong whiles. Because when i had that problem it was because I accidently wrote while true then and it was stuck in the loop.
