TRCV_C instruction
The TRCV_C instruction (Page 520) creates a communications connection to a partner
station. The connection is set up, established, and automatically monitored until it is
commanded to disconnect by the instruction. The TRCV_C instruction combines the
functions of the TCON, TDISCON, and TRCV instructions.
From the CPU configuration in STEP 7, you can configure how a TRCV_C instruction
receives data. To begin, insert the instruction into the program from the "Communications"
folder in the "Instructions" task card. The TRCV_C instruction is displayed, along with the
Call options dialog where you assign a DB for storing the parameters of the instruction.
