Chapter 2 Use CIP Symbolic Client Messaging
Create CIP Symbolic Program (Read)
The previous program illustrated how a write instruction is sent from Controller A to Controller B using the
MSG_CIPSYMBOLIC function block. This section shows how Controller A reads the value of Controller B’s global
variable, UDINT_ToA.
At the end of these instructions, you should have created the following program in Connected Components Workbench in
your Controller A project.
What’s the value of Global
Variable UDINT_ToA?
