Modbus Server Settings
: Modbus can be configured to operate over serial RS232 or RS485 and
in this case Serial port physical parameters and Slave ID (1...256) can be configured. Modbus can
also be configured to work over TCP/IP and in this case the network setting parameters apply.
Output Channel Settings:
for each output the Insulation Alarm can be masked (bypassed).
Logging can be disabled or log data cleared for each output.
The log files (one per each output and per each Start command) can be downloaded connecting
with to a network share (replace IP address with the correct one):
192.168.1.10\negpower
Log files are stored in RAM so they are lost after power off cycle.
NEG POWER is able to detect the Output Insulation Losses making a check between
positive/negative power wire and ground wire or between thermocouple wires and ground wire.
In some system it is possible that the negative power wire and ground wire are shorted. NEG
POWER detects this particular condition as an Insulation Loss and shows an alarm. In order to
avoid this situation, it is possible enable/disable this check.
