*2 The slave module alarm signal and parameter access error are maintained until Error reset request flag (RY0) is turned on. Errors are
stored in the appropriate memory areas.
No. Description
(1) Parameter access starts when one of the following signals is turned on by programs.
*1
• Slave module parameter access request command (RY10)
• Slave module parameter batch read command (RY11)
• Slave module parameter batch write command (RY12)
(2) The operation in (1) turns off Parameter access completion flag (RX11).
(3) The parameter access is in progress.
(4) After checking that Parameter access completion flag (RX11) is off, the signal that was turned on in (1) is turned off by using the program.
(5) When the signal of (1) is off and the parameter access is completed, Parameter access completion flag (RX11) automatically turns on.
To read the parameters, perform the following.
After the Parameter access completion flag (RX11) turns on, use the SLMPSND instruction to acquire the start address where the parameters of
the access target ID are stored from the parameter storage location memory address.
For details on the SLMPSND instruction, refer to the following.

(6) If parameter access has an error, Parameter access error (RX12) turns off and on and Parameter access completion flag (RX11) automatically
turns off and on.
*2
(7) When Error reset request flag (RY0) is turned on by programs, Slave module alarm signal (RX10) and Parameter access error (RX12) turn off.
