Omron G7, F7, L7, E7 manual Specifications, Input specifications, High-speed counter inputs

Item		Specifications
		3G3RV-P10ST8-E	3G3RV-P10ST8-DRT-E
Power-interruption hold function		Holds the contents of HR, AR, CNT, and DM areas.
Memory backup (see notes 1 and 2.)		Flash memory: Program, read-only DM area, and PC setup
		Memory backup: The read/write DM area, HR area, AR area, and counter values are backed up.
		(The battery has a 5-year lifetime at 25 °C and it is replaceable.)
Self-diagnostic function		CPU errors, memory errors, communications errors, setting errors, battery errors
Program check		No END instruction, program errors (regularly checked during operation)
Connected tools	CX-programmer	After version 2.1
	Programming console	C200H-PRO27, CQM1-PRO01
	SSS	PC98 & PC/AT (SYSMAC support software, all versions)
	CX-drive	Version 1 or higher

Note: 1. The DM area, HR area, AR area, and counter values are backed up. If the backup battery or capacitor is discharged, the contents of these areas will be lost and the data values will revert to the defaults.

2.The contents of the program area, read-only DM area (DM6144 to DM6599), and PLC setup (DM 6600 to DM 6655) are stored in flash memory. The contents of these areas will be read from flash memory the next time the power is turned ON, even if the backup battery or capacitor is discharged.

When data has been changed in any of these areas, write the new values to flash memory by switching the 3G3RV-P10ST to MONITOR or RUN mode, or by turning the power OFF and then ON again.

3.Changes made while in MONITOR mode using, for example, online editing, are written to flash memory in real-time.

4.The above figure for power consumption includes the power consumption of the programming console.

5.This input is shared by the high-speed counter and synchro- nized pulse control functions.

6.This output is shared by the pulse output and synchronized pulse control functions.

High-speed counter inputs

The following unit input bits can be used as high-speed counter inputs. The maximum count frequency is 5 kHz in differential phase mode and 20 kHz in the other modes.

Input	Function
	Differential phase mode	Pulse plus direction input mode	Up/down input mode	Increment mode
IN 00000	A-phase pulse input	Pulse input	Increment pulse input	Increment pulse input
IN 00001	B-phase pulse input	Direction input	Decrement pulse input	Normal input
IN 00002	Z-phase pulse input or hardware reset input (IN00002 can be used as a normal input when it is not used as a high-speed counter input.)
