Page 18: Configuring The Display
3–5 Configuring the Display The TEC-220 can be configured to display the process value by selecting PV for DISP or to display the set point value by select- ing SP1 for DISP. If LOCK is set to NONE, OUT2 is set to DEHI, and DISP is set SEL1=SHIF, SEL2=ADDR. -
Page 19: Pv Shift
3–8 PV Shift In certain applications it is desirable to shift the controller display value from its actual value. This can easily be accomplished by using the PV shift function. The SHIF function will alter PV only. Here is an Example: A process is equipped with a heater, a sensor, and a subject to be warmed up. -

Chapter 4 Applications 4–1 Heat Only Control with Dwell Timer An oven is designed to dry products at 150°C for 30 minutes and then stay unpowered for another batch. A TEC-920 equipped with dwell timer is used for this purpose. The system diagram is shown at right: To achieve this function, set the following parame- ters in the setup menu:... -

4–3 Heat-Cool Control An injection mold is required to be controlled at 120°C to ensure a consistent quality for the parts. An oil pipe is buried in the mold. Since plastics are injected at a higher temperature (e.g., 250°C), the circulation oil needs to be cooled as its temperature rises. -

Chapter 7 Modbus Communications This chapter specifies the Modbus Communications protocol as RS-232 or RS-485 interface module is installed. Only RTU mode is supported. Data is transmitted as eight-bit binary bytes with 1 start bit, 1 stop bit and optional parity checking (None, Even or Odd). -
Page 30: Exception Responses
7-2 Exception Responses If the controller receives a message which contains a corrupted character (parity check error, framing error etc.), or if the CRC16 check fails, the controller ignores the message. However, if the controller receives a syntactically correct message which contains an illegal value, it will send an exception response, consisting of five bytes as follows: slave address +offset function code + exception code + CRC16 Hi +CRC16 Lo Where the offset function code is obtained by adding the function code with 128 (ie. - Page 31 Register Parameter Parameter Scale Scale Notes Address Notation High ALFN Alarm Function 65535 REHI Retransmission high scale value ALMD Alarm operation mode 65535 ALHY Alarm hysteresis ALFT Alarm failure transfer 65535 COMM Communication function 65535 ADDR Address 65535 BAUD Baud rate 65535 DATA Data bit count...
