2) Transmission trigger conditions
The transmission trigger conditions designate the conditions
interpreted by the R2 as a data transmission trigger generation when
monitoring the monitor target statuses.

The transmission trigger is
generated when the R2
detects a change in each
status.
*1 When the parameters have been set with the GPP function or RLPA
command, the master station CPU's RUN/STOP status will be the
trigger generation conditions.
If the parameters have been set with the sequence program, the ON
or OFF of the master module's refresh indication (Yn0) will be the
trigger generation condition.
ON : CPU operation status running
OFF : CPU operation status stopped
*2 The CPU error will be the condition of generating a trigger for an error
related to the stopping of the CPU.
Refer to the CPU module User's Manual for details.
(c) Transmission data designation area (
R2
79H, 7BH,
F5H, F7H)
1) When monitoring the device/status with the monitor target designation,
the designation destination of the data to be transmitted if the R2
detects the transmission trigger generation is designated.
2) For the transmission data designation, the head No. of the transmission
table in which the transmission data is designated and the transmission
table size are designated for the R2 transmission table (
R2
122H to
185
H).
