Table 2 - I/O channel functions
During the configuration of channels, only the valid options for each
channel will be shown on the display. The description for the
functions follows:
•
off
- No function
The I/O channel programmed with code
off
will not be used by the
controller.
Note: Although without function, this channel is available through the
serial communication (command 5 MODBUS).
•
A1
,
a2
,
a3
,
a4
– Alarm output
The selected channel can be used as output to alarms. Available for
all the I/O channels.
•
(trL
- PWM control output
Defines the channel to be used as control output (relay or digital
pulse). Available for all the channels. The digital pulse is available
on (when available) and I/O5.
•
mAn
–Digital input with Manual/Auto function
Defines the channel as Digital Input with the function of switching the
control mode between Automatic and Manual. Available for I/O3,
I/O4 (when available) and I/O5.
Closed Contact =Manual control / NO
Opened Contact = Automatic control / YES
•
rvn
- Digital input with
RUN
function
Defines channel as Digital Input with the function of enabling / disabling
the control and alarm outputs (“
RvN
”:
YES / no
). Available for I/O3,
I/O4 (when available) and I/O5.
Closed Contact = Outputs enables / NO
Opened Contact = Outputs disables / YES
•
rsp
– Digital input with remote SP function
Defines channel as Digital Input with the function of selecting the
remote SP. Available for I/O3, I/O4 (when available) and I/O5.
Closed Contact=Remote SP
Opened Contact = Main SP
•
kprg
– Digital input with
Hold Program
function
Defines channel as Digital Input with the function of commanding the
execution of the selected setpoint profile program. Available for I/O3,
I/O4 (when available) and I/O5.
Closed Contact = Enables execution of the program
Opened Contact = Interrupts execution of the program
Note: Even when the execution of the program is interrupted, the
control output remains active and controlling the process at the point
(Setpoint) of interruption. The program will resume its normal
execution starting from this same point when the digital input is
closed.
•
Pr 1
– Digital input with function to Execute Program 1
Defines the channel as Digital Input with the function of commanding
the execution of the setpoing profile program 1. Available for I/O3,
I/O4 (when available) and I/O5.
Useful function for switching between the main setpoint and a
secondary one defined by the program 1.
Closed = selects program 1
Opened = useds main Setpoin
•
(.0.20
–0-20 mA Control Output
Available for I/O 5 only, defines the channel as a 0-20 mA control output.
•
(.4.20 -
4-20 mA Control Output
Available for I/O 5 only, defines the channel as a 4-20 mA control output.
•
P.0.20
– 0-20 mA PV retransmission
Available for I/O 5 only, configures the channel to retransmit the PV
measurement in 0-20 mA.
•
P.4.20
- 4-20 mA PV retransmission
Available for I/O 5 only, configures the channel to retransmit the PV
measurement in 4-20 mA.
•
s.0.20 –
0-20 mA SP (Setpoint) retransmission
Available for I/O 5 only, configures the channel to retransmit the
values of SP in 0-20 mA.
•
s.4.20 –
4-20 mA SP (Setpoint) retransmission
Available for I/O 5 only, configures the channel to retransmit the
values of SP in 0-20 mA.
ALARMS FUNCTIONS
The controller has 4 independent alarms. They can be programmed
to operate with eight different functions, represented in Table 3.
•
off
– Alarms turned
off
.
•
ierr
– Sensor break alarm
It is activated whenever the input sensor is broken or disconnected.
•
rs
– Ramp & soak program event alarm
This alarm is activated by the Ramp & Soak program (refer to the
PROGRAMS OF RAMP AND SOAK section on how to set the event
alarm).
•
lo
– Alarm of Absolute Minimum Value
It is activated when the measured value is below the value defined in
the alarm Setpoint.
•
ki
– Alarm of Absolute Maximum Value
It is activated when the measured value is above the value defined in
the alarm Setpoint.
•
dif
– Alarm of Differential Value
In this function, the parameters “
SPA1
”, “
SPA2
”, ”
SPA3
” and “
SPA4
”
represent the PV deviation as compared to the main SP.
Using the Alarm 1 as example: for Positive SPA1 values, the
differential alarm will be triggered when the PV value is out of the
range defined in:
(SP –SPA1) to (SP + SPA1)
For a negative SPA1 value, the differential alarm will be triggered
when the PV value is within the range defined above
•
difl
– Alarm of Minimum Differential Value
It is activated when the PV value is below the value defined in:
(SP –SPA1)
Using the Alarm 1 as example.
•
difk
– Alarm of Maximum Differential Value
It is activated when the PV value is above the value defined in:
(SP + SPA1)
Using the Alarm 1 as example.
