4-10 Configuration and Programming

Mode 3 Example

In the Module Setup block below, four ranges are assigned to Counter

1. Eight ranges are assigned to Counter 2. Two ranges are assigned to

Counter 3. The last two ranges are assigned to Counter 4, but the

counter is not specified.

Counter Configuration

Block

Figure 4.5 shows the format of the Counter Configuration Block. This

block programs the following parameters of the selected counters:

• Counter Type

• Input Configuration

• Gate/Preset Mode

All four counters can be programmed with one block. When this

programming block is sent to the module, the selected counter(s)

cannot be running or a programming error results. Sending this

programming block to the module erases all programmed output

ranges of the selected counter(s).

IMPORTANT

The number of ranges for the last configured counter

used must equal zero, otherwise the module fills in

the value and errors, even if the value is correct.
