2221H • The set value is out of the range. Or the
setting values of the master station and
local stations are not consistent.
• When executing the CCPASETX
instruction, CCPASET instruction, or
M_RJ71GN11_SetParameterX, the
settings of the master station and slave
stations in the network configuration
setting data are not consistent.
• Parameters that are not supported by the
firmware version of the network module
have been set.
• The engineering tool does not support the
parameters that are required to execute
the set functions.
• Check the detailed information of the error by executing module
diagnostics using the engineering tool, and correct the parameter setting
corresponding to the displayed parameter number.
• After reviewing whether the settings of the master station and slave
stations are consistent in the network configuration setting data, execute
the CCPASETX instruction, CCPASET instruction, or
M_RJ71GN11_SetParameterX again.
• Check the firmware version of the network module. If parameters that are
not supported are set, update the firmware version or correct the
parameters.
• Update the version of the engineering tool, and then retry the operation.
