32-Channel Analog Input Module

Quantum Series 140 AxI 05x 00sc

6.2 Demultiplexing Channel Data - Autosequence Mode

The autosequence mode of operation is intended to simplify the

demultiplexing of channel data from the eight input registers into storage

for the 32 channels. The Autosequence Mode is enabled under the

following conditions:

• Input Mode = Data Mode (Configuration Word Bits 11 & 12 = 0)

• Autosequence Disable is not active (Configuration Word Bit 10 = 0)

In the autosequence mode, the group select bits in the configuration word

are ignored. Instead, the module samples channel data in groups of eight

(8), presents the data to the PLC and then scans the next group automati-

cally.
