5.5. Transducer functions
5.5.1. Measurement input
The PCE-P30U transducer is equipped with universal, configurable
measurement input, which enables to measure direct current, direct
voltage, resistance and temperature from thermocouples and thermi-
stors. Detailed information about supported inputs is shown in table 48.
Input type RS-485 is a special type of input, in which transducer treats
value form register 8000 as a measured value. Value in register 8000
depends on
RS-485
interface working mode (Slave, Monitor or Master)
and can be written, monitored or read via RS-485 interface.
5.5.1.1. Interface RS-485 Master mode
RS-485 interface can work in
Master
mode, in which device is able
to read data registers from one slave device connected to transdu-
cer. Both devices must have the same communication parameters.
The RS-485 Master mode is switched on by selecting the appropriate
mode of RS-485 interface from menu:
