Device
SR1332 Remote backplane ID
SR1333 Remote slot ID
Extension communication
SR1334
port number
SR1335 Cycle of a PLC Link
Number of slave stations
SR1336
connected
Time for which data has
SR1337 been exchanged by
means of a PLC link
Restricted time of the PLC
SR1338 link which is defined by
users
Name R/W
The value in SR1332 indicates the remote backplane
R/W on which the RTU module used is installed. The value
in SR1332 must be in the range of 1 to 8.
The value in SR1333 indicates the remote slot in
R/W which the RTU module used is installed. The value in
SR1333 must be in the range of 0 to 7.
The value in SR1334 indicates the communication
R/W
port used. The value in SR1334 must be 1 or 2.
The value in SR1335 indicates the time it takes for the
master station to detect all the slave stations. (Time
unit: 1 millisecond)
The value in SR1335 will be 0 if one of the following
conditions occurs.
R 1. The master station is turned from OFF to ON.
2. The master station begins to runs, or stops running.
3. The master station finishes detecting all the slave
The value in SR1335 will remain unchanged if the
function of enabling a PLC Link is disabled.
Users can not set SR1336. The can only view the
value in SR1336. Whenever a PLC Link is executed,
R
the slave stations connected to the master station are
count.
The value in SR1337 indicates the number of times the
master station exchanges data with all the slave
stations. SR1337 can be used only if SM1587 is ON. If
the execution of a PLC link stops, the value in SR1337
R will not disappear. If the execution of a PLC link in the
manual mode stops, the value in SR1337 will not
disappear. If the value in SR1337 becomes the same
as the value in SR1338, the execution of the PLC link
in the manual mode will stop.
Users can set the number of times the master station
exchange data with all the slave stations.
R/W The value in SR1338 must be in the range of 1 to
65535. If the value in SR1338 is not in the range, it will
not be changed automatically.
