When the module specified by Un is not an intelligent function module.
When the module specified by Un is not a special function module.
When an attempt was made to execute an unsupported instruction.
When the number of devices in the instruction is incorrect.
When the instruction specifies a device that cannot be used.
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: 8 points
• Device station setting data: 64 points
• Reserved station specification data: 4 points
• Error invalid station specification data: 4 points
• Send, receive and automatic refresh buffer assignment data: 78 points
Example: Assume that data registers D0 to D12287 are available for the L02CPU. If the device
head number of the device station setting data is set to D12284 when there are only 4 device
stations, an error indicating that the available range is exceeded occurs because the programmable
controller CPU checks the range from D12284 to D12347 (for 64 stations).
