Honeywell SC-UCMX01 51307195-175 module

Modifications which have been performed on a running PLC program and which have been enabled are rejected again. In addition, the PLC restores the old program status. The old program status is the status of the program which existed before the program modification, i.e. before entry of command AEND in the PLC. After command ALT is entered, the old program status is reactivated within approximately 1 ms without further intervention on the part of the user. The command can be used if the user recognizes that the program modifications implemented do not achieve the intended result.

The PLC’s present capacity utilization is displayed in percent. This display indicates to what extent the capacity of the PLC is being utilized owing to execution of the user program. The processor capacity which corresponds to the difference between 100 % and the capacity utilization display is available for operation of the serial interfaces, i.e. for communication with the devices connected to the serial interfaces. The utilization should not be greater than 95 % for the longest program path so that communication is still possible via the serial interfaces. Note that the capacity utilization of the PLC is also determined by the current program branches (conditional branches and consecutive number blocks). Note: The capacity utilization display provides a correct indication of the utilization caused by the user program only if no communication is occurring via the serial interfaces at the instant of display.

Search for string in user program (Find)

adr: Start address as of which searching is to be carried out. If no start address is entered, searching is performed as of address 0. string: Maximum 8 commands, i.e. 16 words of the intermediate code. Function: The user program memory is searched for the string entered by the user as of the entered start address through to the end of the user program memory. If the string is found, the address is displayed. If the string occurs several times in the program, the next program address which corresponds to the string is displayed in each case if you enter a semicolon (;). Example: F, E 0,0 & E 0,1The entered string is sought as of the program memory start address 0. F 100, !BA1Block call 1 is sought as of the program memory start address 100. Enable a program change on a running PLC program

Display program identification

Before entry of command FREI, the program modifications performed are not yet executed by the PLC. After entry of command FREI, the modifications performed are executed by the PLC. Command ALT can be used to reactivate the old program status. The functionality of the PLC program can be further–modified by a further program modification.

Function: The identification entered by the user for the user program is displayed. If no identification has been issued for the program, nothing is displayed either (see also command: IDS).

The identification entered by the user for the user program is stored in the program memory. The identification may comprise maximum 16 characters. It serves, for instance, to store the project name and the creation date of the program in the PLC.
