3. Executing the PMCR( ) instruction
4. For details on confirming operation, see Section 12 Tracing and I/O Mem-
ory Monitoring in the CX-Protocol Operation Manual (W344).
• Transmission Line Tracing
The data in the send/receive messages flowing over the transmission
line (RS-232C or RS-422A/485) and the control codes are traced.
• I/O Memory Monitoring
Monitors send/receive data and the status of the various flags.
Using User-created Protocols
PMCR(—)
Section references in the following procedure refer to the CX-Protocol
Operation Manual (W344).
1. For details on designing protocols, see Section 4 and Section 5.
a) Create a communications sequence status transition chart.
b) From the status transition chart, divide the processing contents into
sequence steps.
c) Determine the send/receive message contents.
2. Use the CX-Protocol to create and send a project (protocol data).
a) Creating a new project:
See 5.1 Creating a New Project or Protocol.
b) Creating a new communications sequence:
See 5.2 Creating a New Sequence or 7.1 Setting a Sequence.
c) Creating steps:
See 5.2 Creating a New Sequence and 8.1 Setting a Step.
d) Creating messages:
See 9.1 Setting a Message.
Note After creating messages, steps can also be created by specifying
message names.
