OCAHG 492838402 DCS system card

The PLC program is transferred from the RAM to the Flash EPROM. Character <*> is displayed on the monitor at intervals of approximately 1 second during programming The program is moved from address aa to address ea or from address aa by the specified number of program memory words. The gap which results is filled with NOPs. New program parts can be inserted in this gap. Moving is possible only if the required space is still available at the end of the user program. However, this is checked automatically. Example: V 0,10The program is moved from address 0 to address 10. NOPs are inserted from address 0 through to address 9. V 10 L 20The program is moved from address 10 by 20 program memory words to address 30, and 20 NOPs are inserted.

Execution of the user program is aborted. All outputs (binary and word) are set to zero. The user program can be restarted by entering ”G”. Timers which have been started continue to run independently of the program status in the operating system. They are aborted only by a cold–start or power OFF/ON.

Display breakpoints

All breakpoints of the program are displayed. The address of the start of the command and its content are displayed and not the breakpoint address when the command is issued. Note on service device TCZ: This command can be used only with the following restriction: A maximum of three program memory points at which breakpoints are set can be displayed on the liquid–crystal display (LCD).

Address of the breakpoint to be reset ,: If only specific breakpoints are reset, the individual addresses must be separated by a comma when entering. Function: The breakpoints can be reset individually. Command BRresets all breakpoints of the program.

If several breakpoints are set, the addresses must be separated by a comma when entering. Breakpoints can be set:
to the address of the operand after an assignment character
to the address of a RIGHT BRACKET
to the address of the last parameter of a block
to the address of the end of the program Function: After the program start, the program stops at the first breakpoint. Breakpoints may also be entered with the program running. A maximum of 15 breakpoints may be set.

operator control functions

Advancing to the next breakpoint: If a semicolon is entered, the program runs to the next breakpoint after expiry of the cycle time and displays the program address and the command at this address. If the next breakpoint is not reached after a specific period, owing to a long cycle time, the display operation can be aborted by enteringC if required. If a breakpoint is set to a program point which is not executed, e.g. owing to a branch, the program continues its cycles but with four times the cycle time, which may have a disadvantageous effect on the functionality Pressing keyand key W simultaneously takes you to the monitor program of the PLC. This makes available certain basic functions at the monitor level to the user. If you are in the monitor program, you can switch back to the operating program of the PLC by enteringand W again (see also chapter Monitor functions)
