Functions
The PID controller TRM210 is designed for creating automatic control and regulation
systems of various technological processes in different areas of industry, agriculture and
utilities.
The controller provides following basic functions:
–
measuring of the process value and its transformation according to the sensor type
–
displaying the process values and configuration parameters on two 4-digit LED dis-
plays
–
scaling and filtering of input signal
–
signal correction
–
PID control (pulse or analog) or on-off control
–
autotuning function
–
stand-alone control
–
manual control
–
network control (RS485 interface) with akYtec, Modbus-RTU and Modbus-ASCII
protocols as a Slave
–
signal retransmission using analog output 4-20 mA or 0-10 V
–
alarm output
–
sensor / input error and Loop Break Alarm detection
–
error indication
–
remote start/stop using digital input
–
configuration via the functional keys
1.3
RS485 network
The TRM210 uses the common standard RS485 for data exchange.
Serial interface RS485 enables communication via two-wired line in half-duplex mode.
The device supports the Modbus RTU, Modbus ASCII and akYtec protocols with auto-
matic protocol detection.
