Installation Instructions

32-Channel Analog Input Module

Quantum Series 140 AxI 05x 00sc

The module update rate is determined by the number of channels enabled

and the filter frequencies selected. For example, if all 32 channels are

enabled and the filter frequency for all groups is 60 Hz, then the cycle

time for a full set of 32 channels is 32 x 58 msec or 1.856 seconds.

It takes four ladder logic scans of the eight registers to see all 32 chan-

nels. These four scans must be completed at least twice as fast as the

module update time to ensure no data is missed. In the example above

the ladder scan time would need to run at 1.856 sec/8 or 232 msec or

faster to ensure no data is missed.

The following ladder logic shows how to move data from the 8 multi-

plexed input words to a block of 32 output words starting at location

400101 using the autosequence mode. This example file for use only

with Modsoft programming software can be formed on the install disk

shipped with your module. The file is under the A:\Programs

subdirectory. To install:

1. Insert the install disk into drive A:

2. Copy A:\Programs\QAI32_AC.* C:\Modsoft\Programs

3. Select File QAI32_AC under Modsoft to run. The I/O map is as follows:
