PARAMETER Commands: Query settings and set parameters With the parameter commands, all functions of the Process Unit 73 LF can be defined via the computer interface (with the exception of the interface transmission parameters). With the parameter commands, all instrument parameters can be read and written! Therefore, the correctness of the transmitted commands is particularly important. Transmission in the point-to-point mode is not secured with checksums. To avoid incorrect settings, it is therefore advisable to read back important parameters for a comparison. With the first write command, the controlling computer (PC, SPS, ...) assumes control of the Process Unit 73 LF. Many security prompts must then be implemented in the computer! With the “WCOMIN0” command (go to local) the computer returns control to the Process Unit 73 LF. The Process Unit 73 LF restarts in the measuring mode. Read commands cause no status changes and do not influence the system functions. The Process Unit 73 LF continues to be in control. When the write protection is switched on, any write attempts without switching off the write protection beforehand or with an invalid passcode are entered in the logbook. As delivered, write protection is switched off. If parameter setting is called up with the device keypad, the NAMUR message Functional check is set. Warning and failure contacts are deactivated until parameter setting is completed. If device parameters are changed via the RS 485 interface, all messages are released. As a result, temporary messages may occur when changing parameters which would have been suppressed had the keypad been used. WCOM01 WCOU1 With the “WCOM01” interface command, the device can be switched to the parameter setting mode. The NAMUR message Functional check is then set and with it the warning and failure contact also deactivated in the interface mode. Return to the measuring mode with “WCOM00”. If all device functions are to be frozen during parameter setting, use the “WCOU1” command. The Functional Check is set, and the warning and failure contact deactivated. The output current and controller are also frozen and the limit-value contacts are inactive. Unfreeze the device functions with “WCOU0”.
