(4) Operation error
In the following cased, an operation error occurs; the error flag (SM0) turns ON
and the error code is stored in SD0.
Error code
2112 When the module specified by Un is not an intelligent function module.
4002 When an attempt was made to execute an unsupported instruction.
4003 When the number of devices in the instruction is incorrect.
4004 When the instruction specifies a device that cannot be used.
4100 When the instruction contains the data cannot be used.
When the number of points for data used in the instruction exceeds the available
range, or storage data and constants of a device specified by the instruction
exceeds the available range (including dummy devices).
The number of points required for each data is shown below.
• Control data
• Slave station setting data
• Reserved station specification data
4101
• Error invalid station specification data
• Send, receive and automatic refresh buffer assignment data
Example: Assume that data link registers D0 to D12287 are available for the
Q02CPU. If the device head number of the slave station setting data is
set to D12284 because there are only 4 slave stations, the PLC CPU
nonetheless checks the range from D12284 to D122347 (for 64 stations)
and an error indicating that the available range is exceeded occurs.
