Communication Chapter 4
Ethernet PCCC/CSP protocol
You may set up messaging from legacy controllers such as PLC-5 and
SLC 500 controllers, to a power monitor with optional Ethernet
communication, by using peer-to-peer message instructions. In the
message setup, specify the controller data table address, size of the
data in elements and the channel the message instruction is to use.
For the target device (power monitor), specify its IP address and data
table address. In the example message setup dialog below, the SLC
500 controller is reading the Power table (F17:0) from a power
monitor with IP address 192.1.1.207.
SLC 5/05 Controller to Power Monitor Message Detail Screen Example
If you want to execute a sequence of messages, condition each
message in the sequence with the previous message’s done or error
status, and include a brief programmed time delay between messages
so that each message receives fresh data and the communication port
is not overloaded. As a starting point, program the inter-message time
delay at 100 ms.
