SADRMEM Serial address in memory
Modbus address read/write holding register 1
resolution
and unit of me-
asure
1
range 1 to 255
default 1
Parameter in the memory used to identify the individual controller,
making it available to a supervisor network.
DELAYMEM Response delay in memory
Modbus address read/write holding register 2
resolution and unit of measure 1%
range 0 to 100
default 100
Parameter setting the delay in response to the control step.
0 to 100 = 0-10 sec
MAXMEM Maximum value in memory
Modbus address read/write holding register 3
resolution and unit of measure 1%
range 0 to 100
default 100
Parameter corresponding to the maximum output voltage value.
0 to 100 = 50-100% output
MINMEM Minimum value in memory
Modbus address read/write holding register 4
resolution and unit of measure 1%
range 0 to 100
default 100
Parameter corresponding to the minimum output voltage value.
0 to 100 = 0-40% output
TEMPALM+ Maximum temperature threshold
Modbus address read/write holding register 5
resolution and unit of measure 1
range -30 to 105°C
default 85 °C (85)
Value of the high temperature threshold
TEMPER >= TEMPALM+ then the temp. alarm (ALRTMP) is activated,
hysteresis 3°C.
TEMPALM- Minimum temperature threshold
Modbus address read/write holding register 6
resolution and unit of measure 1
range -30 to 105°C
default -20°C (148)
Value of the low temperature low threshold
TEMPER <= TEMPALM- then the temp. alarm (ALRTMP) is activated,
hysteresis 3°C.
INMEM Input override value
Modbus address read/write holding register 7
resolution and unit of
measure
1%
range 0 to 100
default 0
Input value for the override input option (IOVR = 1)
DELAYINMEM Response delay
Modbus address read/write holding register 8
resolution and unit of
measure
1%
range 0 to 100
default 100
Parameter for response delay of memory input (INMEM)
0 ÷ 100 = 0-10 sec
ALMO Output value in the event of alarms
Modbus address read/write holding register 9
resolution and unit of measure 1
range 0/1/2
default 0
Output value in the event of alarms
ALMO 0 0% O
1 50%
2 100%
OUTMEM Output value for override
Modbus address read/write holding register 10
resolution and unit of measure 1%
range 0 , OUTMIN to OUTMAX
default 0=Spento
Output value for the override output option (EOVR = 1)
TIMEOUTL/
TIMEOUTH
RS485 timeout value
Modbus address
read/write holding
register 11 & 12
resolution and unit of measure 1
range 0-255 HR11 / 0-5 HR12
default 30 HR11 / 0 HR12
Timeout value for the 485 serial line. After this time, the link LED goes o
and the output goes to ALMO only if input override is enabled (IOVR = 1)
TIMEOUT = TIMEOUTH*256+TIMEOUTL (seconds) (15 to 12,000)
TIMESAVE Saving timeout value
Modbus address read/write holding register 13
resolution and unit of measure 1
range 0-255
default 5
Timeout value for saving the values, expressed in minutes. After this time,
any parameters that have been changed are saved to memory
