Verifying Output Operation
You can directly control each output using the output command 0. Using this command you
can force any output to the desired state, in order to do this the output must be configured as
a programmable output (function A).
> 1O1X0 Turn output 1 on, ignore output 2 and turn off
output 3.
Using Programmable Outputs
Programmable outputs can be used to interface with other parts of the system in order to
indicate such things as in position, sequence in progress, fault or a user defined function.
The following steps demonstrate how you can configure these outputs.
Example
Output 1 is to be configured as a composite fault output. Output 3 is to indicate when the
motor is moving and Output 5 is to indicate when the motor is in position.
1SSD1 Set output 1 as composite fault
1OUT3B Set output 3 as moving / not moving
1OUT5T Set output 5 as in position output
Typing 1OUT will display
Sequences
Introduction
A sequence is a series of commands that is executed in order whenever the sequence is run.
Immediate commands cannot be stored in a sequence since they cannot be stored in the
command buffer. The only "saveable in sequence" commands are buffered commands.
The positioner has a section of non-volatile RAM totalling 8000 characters allocated for
storing up to 64 sequences. The sequence buffers are of variable length, so they can store
long sequences of up to 8000 characters or several shorter ones, provided that the total
length of all sequences does not exceed the allocated 8000 character space.
During normal operation a command can specify the execution of any sequence stored in
memory.
Sequence identifiers: number from 1 - 64.
When a sequence is programmed, the positioner automatically calculates a checksum for the
sequence and stores the length of the sequence and its checksum in an internal directory.
The command XSS can be used to verify the existence of a sequence.
