Protocol Macro Data - Omron CJ Series Connection Manual

9.6. Protocol Macro Data

The protocol macro data consists of sequence, step, send/receive message, and receive
matrix. Its composition is described as follows:
●When there is only one receive message format for a step (send/receive once)
・Set one each of receive and send messages for the step.
Sequence No. 900
・
・
Sequence No. xxx
●When there are several types of receive message formats for a step (send/receive once)
・Set the send message and the receive matrix for the step.
・Store several types of receive message formats in the reception matrix case numbers 00
to 14. (In the case number 15, "Other" is automatically stored.)

9.6.1. Composition of Protocol Macro Data
In the protocol macro data, there are three different types of receive message formats (normal
and error messages) for the send message (SD_VR). Therefore, the following composition is
used with the receive matrix (Mat_VR).
Sequence No. 900
*Normal message for receiving: RV_VR
Error message for receiving: RV_ER, Other
(For details, refer to 9.6.6. Receive Message Settings.)
