Configuring the TSEND_C instruction transmit (send) parameters
TSEND_C instruction
The TSEND_C instruction (Page 401) 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 TSEND_C instruction combines the
functions of the TCON, TDISCON and TSEND instructions.

displayed, along with the Call options dialog where you assign a DB for storing the
parameters of the instruction.
You can assign tag memory locations to the inputs and outputs, as shown in the following
