6-3 Lamps, Touch Switches, and Numeral Setting

This section describes bit allocation for lamps and touch switches and the method used to find the numeral input using the numeral setting function, when communi- cating with the PC using the Host link/NT link/C200H direct.

Reference For details on lamps, touch switches and the numeral setting function, refer to 5-6 Lamps (page 135), 5-7 Touch Switches (page 138), and 5-8 Numeral Setting (page 143).

6-3-1 Allocation Bits and Display of Lamps

Lamps are controlled by allocating them to the PC bits. Set the area and bit num- ￿ber.

Available allocation bits

The lamps can be allocated to the following PC areas:

Symbol	C Series PCs	Allocated	CVM1/CV Series PCs	Allocated
DM	Data memory	✓	Data memory	✓
CH	Internal/Special Relay	✓	Internal/Special Relay	✓
TIM	Timer		Timer
CNT	Counter	￿	Counter
HR	Holding Relay	✓	--
AR	Auxiliary Relay	✓	Auxiliary Relay	￿
LR	Link Relay	✓	--
			✓ : OK ￿: NG

To set the data memory (DM), specify the word number and then the bit number (00 to 15).

Reference Since the special auxiliary relays of the CVM1/CV series PCs are allocated to the system, they cannot be used for purposes other than the system use.

The range of respective area varies with the type of PC. Refer to Appendix L PC ￿Memory Map (page 291).

Controlling the lamps in batch

More than one lamp can be lit or flashing in batch by registering those lamps to the same bit.

[Example of batch lighting]

Set the lamps L1 to L5 to the same bit number.
