4.13 Slave Module Parameter Read/Write
Parameter access timing
The parameter access timing is as follows.
*1 Before the start of parameter access from the FX5-ASL-M 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.)
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' (Un\G27 b8)
• 'Parameter batch read command for the slave module' (Un\G27 b9)
• 'Parameter batch write command for the slave module' (Un\G27 b10)
(2)
The operation in (1) turns off 'Parameter access completion flag' (Un\G28 b9).
(3)
The parameter access is in progress.
(4)
When parameter access (read/write) is completed, 'Parameter access completion flag' (Un\G28 b9) automatically turns off and on.
(5)
If parameter access has an error, 'Parameter access error' (Un\G28 b10) turns off and on and 'Parameter access completion flag' (Un\G28 b9)
automatically turns off and on.
(6)
Turning off and on 'Error flag clear command' (Un\G27 b0) with a program turns on and off 'Parameter access error' (Un\G28 b10).
