Load Values The following table shows the load values.

Zeros in the 4X registers also mean no change. Setpoint, maximum count and

assert time can only be set to zero using the Modzoom screens. When the registers

in this example are echoed, zeros will appear but the actual content in the module

will be unchanged from previous values. In this example, Counter 2 is disabled and

its outputs and timed assert have not been selected. Registers 400204 - 6 have no

meaning.

After the module executes the Configure and Load Value’s commands, they are

echoed in the I/O mapped 3X registers except for the command register’s low 8 bits.

Command execution time by the module is 1 ms. Actual time between the 4X

on User Logic and hardware configuration. An echo of the Configuration command

registers would appear as follows:

Response for

Configuration

Command

The following table shows the echo response for the configuration command.

400201 0243 LOAD VALUES command, disable Counter 2, preset and enable

used)
