If the total communication traffic of the
connected display unit exceeds the upper limit of the maximum
constant communication traffic, the slave that has attempted
connection will be refused access. In addition, if the upper limit
is exceeded by the master display unit only, slave display units
cannot connect.
Create your project considering data traffic.
For the upper limit of data traffic and how to calculate it, refer
to the following.
7.6.2 Procedure - How to
Calculate the Communication Traffic
-
Create screens so that the total of continual
communication traffic of all screens does not exceed 8090. If the
total continuous communication traffic exceeds the upper limit, the
slave that has attempted connection will be refused access. In
addition, if the upper limit is exceeded by the master display unit
only, slave display units cannot connect.
-
Ensure that the total number of parts addresses
and device addresses is 475 or less. Otherwise an excessive load is
placed on the Master, which may cause errors and/or access
failure.
-
The Pass-Through feature, Device Monitor feature,
and Ladder Monitor feature cannot be used on Slave display units.
If you would like to share values obtained using Extended Script on
a Master with slaves, select Memory Link for the device/PLC and
expand the Extended Script used in the Master display unit with
Memory Link so you can share with the slave display units.
-
Network project files are not loaded on slave
display units. Therefore, you cannot use the
distribution/collection feature of Pro-Server EX. Also, device
address values of PLCs cannot be read with Device Monitor, Symbol
Monitor and the Pro-Server EX API. Device address values of
internal devices (USR, LS) on the display unit can be read.
-
Because Slave display units do not directly
communicate with the PLC, the display unit cannot read
communication error information in system variables or the LS
area.
-
Slave display units reference device/PLC
connected to the Master display unit, which is the same when using
Memory Link. As a result, when using Memory Link the Slave display
unit cannot access the following areas to diagnose and control the
status of Slave display units.
#MEMLINK 0000 to 0019 (System Data Area)
#MEMLINK 2032 to 2095 (Special Relay Area)
#MEMLINK 9000 to 9999 (9000 Area)
