Ch ap te r 2 Co n tro l Reg is te r2 - 2 52_4. Step: includes 2 parameter settings: a setting point X and a Running time T, indicating the setting value (SV) to rise toX degree after the time T. If the setting point X is identical to the previous setting, this process is called a Soak,otherwise a Ramp; therefore this control procedure is also called a Ramp Soak control. The first running procedure ispreset as a Soak control, to set the temperature control to setting point X degree in advanced and keep thetemperature at X degree, at a duration time of T.5. Number of loops: Extra loops to be carried out for the pattern. If set to 1, the pattern will be carried out 2 times.6. Executing step: Number of steps executed for each pattern.7. Execution: Before execution, users need to set up all the parameters. If the setting control is in the running mode, theprogram will start running from the initial pattern and initial step, carrying out commands one by one by their setorders. When the setting control is in the ending mode, the SV will stop at the final setting. When the setting control isin the stop mode and the temperature will be at the value before the stop, by re-selecting to run, the program will startrunning from the initial pattern and initial step. When the setting control is in the pause mode and the temperature is atthe value before the pause, by re-selecting to run, the program will start running from the step where the program waspaused, carrying out the remaining parts. During execution, the SV cannot be set up.2.7 ERROR LED IndicatorWhen the analog input channel out of range is detected, the error code will show up and the error LED will also blinking tonotify. Users can disable this functionality to inactivate the error LED blinking, but the error code will still show up.Page CR Description Setting ValueBasic Setup Page 38 Output out of range K0=LED blinking (default)K1=LED not blinking2.8 RS-485 Communication Setup for DVP02TK-S2.8.1 MODBUS Communication ProtocolFor DVP02TK-S series, MODBUS supports formats such as RTU and ASCII. When RTU is selected, the data length is 8and the following function codes are supported.Function code 03: read multiple words, up to 32 words can be read.Function code 06: write a single word.Function code 10: write multiple words, up to 32 words can be written.2.8.2 Restore to Factory SettingsUsers can restore the RS-485 communication settings back to defaults (9600/7/1/E, station number 1) by switching RUNto STOP and then STOP to RUN after turning on the device within 5 seconds.2.8.3 RS-485 Communication SetupThere are 2 methods to setup RS-485 communication, via TK Wizard and setting the MODBUS address.• TK Wizard (TKSoft): click the Module Information and set up baud rate, transfer mode and then click “Send” tosave the settings.
