7.11.3. External outputs - Control type: as a linear output
The parameters of External outputs in the type of control as a linear output are
(see Fig. 7.94 ):
– Comm.port - this parameter is read only in External outputs menu, it is the Modbus
port number for which the Modbus external output is configured; a description of
Modbus ports configuration and indication of the Modbus port connectors is located
in
Chapter 7.15. MODBUS
,
–
Device
- this parameter is read only in
External outputs
menu, it shows address
and name of the SLAVE device configured in Modbus menu ( Chapter 7.15.3.
Modbus - MASTER mode ),
– Output channel - this parameter is read only in External outputs menu, it shows
output channel number, type of register and data format configured in Modbus menu
(each SLAVE device as defined in a specific address, has its output list individually
numbered),
–
Source
- this parameter contains Logical channels list where the selected logical
channel will be data source for the external output. Data from this source are
calculated according to parameters in
Input levels block and Output levels block,
– Input levels parameter block – data entered here have the same unit as selected
logical channel (source). For this block, parameters are:
•
Lower level – it sets lower limit value, below which, source input signal will be
equal to this value,
•
Upper level
- it sets upper limit value, above which, source input signal will be
equal to this value,
– Output levels parameter block – this block has parameters:
• Lower level – it sets lower limit output signal value, below which, output signal
will be equal to this value,
• Upper level – it sets lower limit output signal value, below which, output signal
will be equal to this value,
•
Alarm level
– it sets output value which have to appear, when alarm state
appears. It occurs when the logical channel which is source for the external
output, returns
Err , Hi or Lo value.
User should remember that the relationship between input and output levels are
described by linear transmission equation, and it is limited by the range, (see
Fig. 7.96 ).
