Mitsubishi — 2.7 Numbering and Functions of Counters [C]

2 Functions of Devices in DVP-PLC  SA/SX/SC series MPU:  EH2/SV/EH3/SV2 series MPU:  Features of counter: Functions of counters: When the pulse input signals of the counter go from Off to On and the present value in the counter equals the set value, the output coil will be On. The set value should be a K value in decimal and the data register D can also be a set value. DVP-PLC Application Manual 2-18 16-bit counting up, for general purpose C0 ~ C95, 96 points. Fixed to be non-latched. Total 235 points 16-bit counting up, for latched C96 ~ C199, 104 points. Can be modified to be non-latched by setting up parameters.

Counter C 32-bit counting up/down, for general purpose C200 ~ C215, 16 points. Fixed to be non-latched. 32-bit counting up/down, for latched C216 ~ C234, 19 points. Can be modified to be non-latched by setting up parameters. 1-phase 1 input, for latched C235 ~ C242, C244, 9 points Can be modified to be non-latched by setting up parameters.

Counter will continue when the SV is reached. Present value On and being retained when the counting reaches SV. On and keeps being On when counting up reaches SV.

Reset to Off when counting down reaches SV. Output contact Reset PV will be return to 0 when RST instruction is executed and the contact will be reset to Off. Acts when the scanning is completed. Acts when the scanning is completed. Acts immediately when the counting reaches its target, has nothing to do with the scan period. Contact action
