(a) Precautions
When there is no high-speed counter with the coincidence detection output setting and no input interrupt within
the range specified in the "Intelligent Function Module Interrupt Pointer Setting" of PLC Parameter,
"PARAMETER ERROR" occurs (error code: 3000).
The following are a correct example and an incorrect example of assigning the interrupt pointers of the high-
speed counter to I50 and higher as shown above.
• Correct setting example
In this case, there is a high-speed counter (for which coincidence detection interrupt is set) within the
range specified in "Intelligent Function Module Interrupt Pointer Setting." Therefore, no error will occur.
Input signal function selection: setting of high-
speed counter X0 and X1
• Incorrect setting example
Although CH2 high-speed counter with the coincidence detection interrupt setting is set, both the counter
and input interrupt settings do not exist within the range specified in the Intelligent Function Module
Interrupt Pointer Setting window. Because of this, an error occurs.
Input signal function selection: setting of high-
speed counter X2 and X3
