Parameter information storage location
The parameter information storage location differs depending on the slave module to be used.
Slave module
Bit output slave module
Bit input slave module or bit I/O combined slave module
Word output slave module
Word input slave module or word I/O combined slave module
Parameter access timing
The parameter access timing is as follows.
Executed in the program
Executed by the RJ51AW12AL
'Parameter access request command for the slave module' (Y10),
'Parameter batch read command for the slave module '(Y11),
'Parameter batch write command for the slave module' (Y12)
'Parameter access completion flag' (X11)
'Parameter access error' (X12)
'Error flag clear command' (Y0)
No. Description
(1) Turn off and on any of the signals below with a program to start parameter access.
• 'Parameter access request command for the slave module' (Y10)
• 'Parameter batch read command for the slave module' (Y11)
• 'Parameter batch write command for the slave module' (Y12)
(2) The operation in (1) turns off 'Parameter access completion flag' (X11).
(3) The parameter access is in progress.
(4) When parameter access (read/write) is completed, 'Parameter access completion flag' (X11) automatically turns off and on.
(5) If parameter access has an error, 'Parameter access error' (X12) turns off and on and 'Parameter access completion flag' (X11) automatically
*2
turns off and on.
(6) Turning off and on 'Error flag clear command' (Y0) with a program turns on and off 'Parameter access error' (X12).
(7) Turn on and off the signal that has been turned off and on in the step (1) with a program.
*1 Before the start of parameter access from the RJ51AW12AL to the slave module, apply the access method, access target ID, and
parameter data to the buffer memory.
*2 Error codes are stored in 'Latest error code storage area' (Un\G10256) and the target IDs are stored in 'Latest error ID storage area'
(Un\G10257). (The latest information is overwritten.)
