Running Sequences
By Command Input
A sequence can be run by entering the XR command immediately followed by a sequence
identifier number (1 - 64) and a delimiter.
Example:
XR3[space] runs sequence No.3
Standalone Operation
Stored sequences may be automatically executed when you power up the system or
executed by remote switches, RP240, TM8 and thumbwheel.
A sequence selected as a binary pattern, set on inputs using the INnO command can be run
in response to a sequence strobe set on an input using the INnB command.
Example
Inputs 1 to 4 are to be used as sequence select lines.
Input 5 is to be used as a sequence strobe line.
Programs have been stored in sequences 1 to 16.
1IN1O Set input 1 as sequence data input
1IN2O Set input 2 as sequence data input
1IN3O Set input 3 as sequence data input
1IN4O Set input 4 as sequence data input
1IN5B Set input 5 as sequence strobe input.
A binary pattern is configured on the inputs corresponding to the decimal sequence number.
On a logic 0 to 1 transition of the sequence strobe input, the sequence corresponding to the
binary pattern will be executed.
If a sequence is already running when the sequence strobe is activated the sequence strobe
will be ignored. A sequence in progress must be terminated before execution of the next
sequence strobe.
Power On Sequence
One of the stored sequences can be designated to be executed when the device is powered
up. The sequence to be executed can be selected by prior RS232C command (XP1-64).
The single sequence specified is executed once; control then passes to the normal command
processor loop. Alternatively, power-on execution can be disabled with either the XP0 or XZ
commands.
It is possible to have the positioner execute a sequence on power up by defining the
commands within a sequence using the XD, XT and XP commands. To define a sequence
you will need to enter:
