On this page, you can select the Global Sequencer operating mode. The mode you choose on this page affects the attributes available in the following pages of the Wizard. The following table provides information on the operating modes. See the Global Sequencer section for more detailed information.

Table 1. Modes
Mode Description
Step Mode

The Sets are controlled in sequence of the device number. The output with the lowest device number is activated first, and the output with the highest device number is deactivated first.

Sequential Mode

The Sets are controlled in sequence according to the first on, first off principle.

Equal Runtime The set with the lowest On time is switched on first, and the set with the highest On time is switched off first.
Equal Startup The set with the lowest Start-up counts is switched on first, and the set with the highest Start-up counts is switched off first.
Binary Code The output stages must form one set and are controlled in sequence according to a binary code principle.
Table 2. Attributes for Basic Configuration
Name Description Mode
Device Capacity This array of analog values represents the capacity of each device output. These values are used to calculate the Make Limit values when Calculate Make-Break Limits is True. When Calculate Make-Break Limits is False, these are ignored and the Make Limits must be set by the user. SP, SQ, ER, BC, ES
Device First Of This value specifies how many devices are in the group where this device is the first of the group. This device and the following (value – 1) devices are grouped together for control. The Device First Of property for the dependent devices of this group are ignored. SP, SQ, ER, ES
Mode Value indicates the operating mode of the sequencer: SP = Step, SQ = Sequential, ER = Equal Runtime, BC = Binary Code, ES = Equal Startup. SP, SQ, ER, BC, ES
Proactive

This value indicates the mode of operation for the sequencer. When this value is set to False, the lead output is activated when the input reaches the first make limit. When this attribute True, the lead output is placed in a continuously activated state (provided Instant Shutdown is set to False) and as such, the second stage is actually activated when Input reaches the first make limit.

Note: Proactive has no meaning when in Binary Code Mode.
SP, SQ, ER, ES
1 SP = Step, SQ = Sequential, ER = Equal Runtime, BC = Binary Code, ES = Equal Startup
