7.18.9 Reading Module Information (UNIRD(P))
The details of the module information are described as follows:
*1: The Universal model QCPU used in the multiple CPU system is turned ON during the online
module change of the module controlled by the other CPU.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
[High Performance model QCPU, Process CPU, Redundant CPU and Universal model
QCPU]
• When n1 is other than 0 to FF
H
(Error code: 4100)
• When n2 is other than 0 to 256 (Error code: 4100)
• When a total of n1 and n2 is equal to or greater than 257 (Error code: 4100)
[Q00/Q01CPU]
• When n1 is other than 0 to 3F
H (Error code: 4100)
• When n2 is other than 0 to 64 (Error code: 4100)
• When a total of n1 and n2 is equal to or greater than 65 (Error code: 4100)
[Q00JCPU]
• When n1 is other than 0 to F
H
(Error code: 4100)
• When n2 is other than 0 to 16 (Error code: 4100)
• When n1 and n2 is equal to or greater than 17 (Error code: 4100)
