CMPx.MODBOUND1

Description

Use this keyword to set the first modulo bound. CMPx.MODBOUND1 and CMPx.MODBOUND2 must both be set before the modulo functionality can be activated. There is no requirement that the second modulus bound be larger than the first modulus bound.

CMPx.MODBOUND1 must be set before CMPx.SETPOINT.

Example

The following example sets the first modulo bound to one billion counts for CMP1.

-->CMP1.MODBOUND1 1000000000
