- Sets
An LoLo
flag used for rules processing. The reset level for
this flag depends on Alarm hysteresis value.
8.2.6.2.3.11. Alarm hysteresis
Function
- Defines alarm thresholds for hysteresis value of analogue
signal (in engineering units).
Data type
- number
Range
- 1....65535 [engineering units]
Default
value
- 10 [engineering units]
Comments
- setting hysteresis value appropriate to signal source variations
prevents overly frequent activation of alarm flags when signal
source is unstable. The value declared here is also valid for
alarm threshold set manually from the front panel of the
module. More about meaning of Hysteresis in chapter Internal
Recourses/SET buttons.
8.2.6.2.3.12. Dead band
Function
- Defines the range of insensitivity for analogue input signal
changes in engineering units
Data type
- number
Range
- 0....65534 [engineering units]
Default
value
- 10 [engineering units]
Comments
- the range of insensitivity stretches symmetrically around
previously noted signal value. Upon signal crosses range, new
signal value is noted so that it is in mid range and a
An DB
flag
is set high in binary outputs space. This flag can be used for
rules processing or trigger recording in Logger .
8.2.6.3. Serial port
Sub-group serial port holds configuration parameters for PORT2.
PORT1 is used solely for module configuration and parameters are unchangeable
(Speed: 9600, 8 bits, no parity, 1 stop bit , flow control: hardware (RTS/CTS).
8.2.6.3.1. Interface type
Function

RS232
voltage interface ±12V, full duplex, three wire,
RS422
differential interface, full duplex, double pair,
RS485
differential interface, half duplex, single pair.
