Equal Relay Numbers
The following table lists all 24 preset register default locations for each high-speed counter.
Each occupies two 16-bit V-memory registers. The corresponding special relay contact
number is in the next column. We might also call these equal relay contacts, because they are
true (closed) when the present high-speed counter value is equal to the preset value. Each
contact remains closed until the counter value equals the next preset value.
The consecutive addresses shown above for each relay are those assigned by the CPU as
default addresses. The Pointer for the start of these addresses is stored by the CPU at V7630.
If you have a conflict of addresses because of pre-existing code written to these addresses, you
can change the default block of addresses merely by having your ladder logic place a different
pointer value in V7630. To change the table location. use the LDA and OUT instructions as
shown on the previous page.
