Module Parameter

This section describes differences in module parameters between the module mounted on the remote head module and CPU
module.
Refresh settings
• Refresh target: Only specified device is selectable. Module label and refresh data register (RD) cannot be selected.
• Transfer to intelligent function module and transfer to CPU: The settable device range is limited. The device range allowed
is as follows.

Data to transfer to the
intelligent function module
Data to transfer to the CPU
module
Automatic serial number assignment of the refresh settings is useful to make a batch access to all the
scattered buffer memory of the intelligent function module existing in more than one area.
• Use the refresh settings of the intelligent function module to make an automatic serial number assignment
of the link register (W) to the buffer memory of the remote head module to perform refresh.
• Master stations are able to read and write from/to the link register (W) of the remote head module with a
single READ/WRITE instruction.
When the master station directly accesses the buffer memory of the intelligent function module with a
REMFR/REMTO instruction, the number of the REMFR/REMTO instructions corresponds to the number of
areas of the buffer memory.
Interrupt settings
The interrupt settings are not available.
If the interrupt settings are set, an error occurs in the remote head module.
Refresh Group
The refresh group setting of the refresh settings is not available.
Parameter setting method
For the RJ61BT11, "Program" cannot be set in "Parameter Setting Method" of "Required Setting".
