Slave module parameter access
The procedures for executing slave module parameter access are as follows.
The G(P).RDMSG instruction is used for the program of slave module parameter access. (

Reading device parameters
1.
Specify the access method.
Store 0000H: read in Parameter access setting (RWwn+16).
2.
Specify the access target ID.
Store the access target ID in Parameter access target module ID specification (RWwn+17).
3.
Turn on Parameter access request command for the slave module (RY(n+1)0).
At this time, Parameter access completion flag (RX(n+1)1) turns off.
In addition, Parameter accessing flag (with handshake) (RX(n+1)B) turns on.
4.
When the parameter access is completed, Parameter access completion flag (RX(n+1)1) automatically turns on.
5.
Turn off Parameter access request command for the slave module (RY(n+1)0).
6.
Parameter accessing flag (with handshake) (RX(n+1)B) turns off when RX(n+1)1 turns on and RY(n+1)0 is turned off.
7.
Read the device parameters from the bridge module to devices in the CPU module by using the G(P).RDMSG
instruction. The following table lists values specified in the setting data of the G(P).RDMSG instruction.
