3 COMMON PARAMETERS
(2) Parameters common throughout the Multiple CPU system
In the Motion CPU, during initialization the parameters in the table below are
verified against the parameters in the PLC CPU of CPU No. 1. Unmatched
parameters generate a PARAMETER ERROR (error code: 3012, 3015), so the
parameters show below must be set identically between Motion CPUs and the
PLC CPU of CPU No.1. (If the system settings are changed in a Motion CPU, it is
necessary to reset. Therefore, the parameters are checked only during
initialization.)
The parameter No. of unmatched parameter is set in the error individual
information (SD16) by this error occurrence.
PLC CPUs can use the parameters of the other CPUs via "Multiple CPU
parameter utilization" of GX Developer. Since Motion CPUs don't have this
function, however, the common parameters must be set for each Motion CPU.
