4.11 Analog Output
The analog output must be selected according to the signal input of the
connected instrument (controller, PLC, etc.).
4.12 Setting of subrange (from / to)
You can choose a subrange (minimum 51 °C) within the basic measuring range of the
pyrometer. This subrange corresponds to the analog output “from“ describes the beginning of
this measuring range, “to“ the end of the range.
Additionally, with the setting of a subrange it is possible to fulfill the requirements of the
“auto” clear mode of the maximum value storage (see 4.10).
4.13 Address
For the connecting of several pyrometers with RS485 with one serial interface
it is necessary to give each instrument an individual address for
communication. First it is necessary to connect each single instrument to give
it an address. After that all instruments can be connected and addressed
individually. If parameters may be changed simultaneously on all pyrometers, the global address
98 can be used. This allows you to program all pyrometers at the same time, regardless of the
addresses that have already been assigned. If the address of a pyrometer is unknown, it is
possible to communicate with it using the global address 99 (connect only one pyrometer).
Note: Only via own communication program with interface command (not
possible with InfraWin, because InfraWin automatically detects a connected
pyrometer): If parameters should be changed simultaneously on all pyrometers, the
global Address 98 can be used. This allows you to program all pyrometers at the
same time, regardless of the addresses that have already been assigned. If the address
of a pyrometer is unknown, it is possible to communicate with it using the global
Address 99 (connect only one pyrometer).
4.14 Baud rate (kBaud)
The transmission rate of the serial interface in Baud (Bd) is dependent on the
length of the cable. A standard cable length with RS232 for 19200 Bd is 7 m,
with RS485 2 km. The baud rate is reduced by 50% if the transmission
distance is doubled.
