SETPOINT
INTRODUCTION
The controller supplied with the Setpoint
programmer option (mod. M5-3… &)
offers, in alternative to the adaptive tun-
ing, the functionality to define, store,
display and execute a program con-
sisting in the Setpoint profile in time.
MAIN CHARACTERISTICS
• 1 program, 16 segments/program
• start, stop, hold etc, commands
from the keyboard
• time base in seconds, minutes or
hours
• continuous or up to 1…9999 time
cycling of the program
• 1 OP3 digital output with the state
profile defined by the program
• setting of the maximum allowed
deviation from the Setpoint
The program consists of a sequence
of segments.
For each segment, it is specified:
• the Setpoint to reach
às.p.
• the duration
of the segment
àt.i.
• the state of the OP3 output
The program consists of:
• 1 initial segment named O
• 1 end segment named f
• 1…14 normal segments
Initial segment
Its main purpose is to define the value
the process variable has to maintain
before starting the program.
End segment
Its main purpose is to define the value
the process variable has to maintain
at the end of the program and until
further changes of Setpoint.
Normal segments
These segments build up the profile
program. There are 3 types of seg-
ments:
àsp.==
Step
àti.== = 0
s.p. = Target setpoint
ti. = Duration
= Previous segment
= Current segment
= Next segment
