6-2 Groups & Modes

Introduction to Groups & Modes (cont’d)

Each group also has an associated Group Channel that is used to signal when group
logic should be reset. Group channels are numbered 90 through 95. Pulses are pro-
grammed into group channels just as they are programmed into output channels.

Group Programming

Output channels are divided into groups through OUTPUT GROUP programming.
When dividing outputs into groups, keep these rules in mind:

• Output channels are assigned to groups sequentially. Group 0 will begin with Output

Channel 0 and include the specified number of channels; Group 1 will begin with the
next output channel and continue sequentially for its specified number of channels;
etc. The last group will automatically include all of the remaining output channels.

Mode Assignments

During OUTPUT GROUP programming, each group is assigned any one of six modes
of operation that control the interaction between the group, its group input, and its group
channel. Detailed discussions of each operating mode follow.

Mode 0 - Straight Cam Logic

Description

Output channels in a group assigned to Mode 0 are not affected by the corresponding
input terminal or group channel.

Details

• MOTION ANDING and OUTPUT ENABLE ANDING can be used with outputs in a

Mode 0 group.

• The machine position for a Mode 0 group can be set through GROUP OFFSET pro-

gramming, Chapter 4.

Mode 0 Programming

During OUTPUT GROUP programming, group together output channels that should
remain unaffected by Modes, and assign them Mode 0.
