6.3 Communication Between Input/Output Module and Intelligent Function Module

6 - 7
This section introduces the settings that are required to allow the CPU module to
communicate with the remote I/O station input/output module and the intelligent
function module using cyclic transmission.
The following example is used to explain this configuration.
Remote master station
Power QCPU QJ71 QX40 QY40P
supply BR11
(a) Remote master station / remote I/O station
Input: X100 to X12F
(X120 to X12F are being used by intelligent function module)
Output: Y110 to Y12F
(Y120 to Y12F are being used by intelligent function module)
(b) Remote master station
(c) Remote master station
Link register W100 to 10F
(Parameter setting examples)
(1) The common parameters and refresh parameters are set in the CPU module.
(2) The intelligent function module parameters (initial settings, automatic refresh
settings) are set using in the remote I/O module. Moreover, switch settings can
also be done by I/O allocation settings, depending on the intelligent function
module used.
Note that when operating with only the input/output module mounted to the
remote I/O module, the default parameters are set in the remote I/O module.
(a) CPU module: Common parameters
Sets the input/output and link register range for communicating between
the remote master station and remote I/O station.
1) XY settings
2) BW settings
