5-1SectionStartup Procedure
61
f) Use the Programming Console to set the SRM1 to PROGRAM mode.
g) Use the Programming Console to set the maximum number of Slaves
(bits 00 to 03 of DM 6603) and the CompoBus/S communications mode
(bits 04 to 07 of DM 6603). (The SRM1’s power must be turned OFF and
then ON again to enable new settings in DM 6603.)
h) Check that the “SD” and “RD” indicators light.
2. I/O Wiring Checks
a) With the SRM1 in PROGRAM mode, check the output wiring by turning
on the output bits with the force set and force reset operations.
Refer to 4-2-25 Force Set, Reset for details.
b) Check the input wiring with the SRM1’s input indicators or the Program-
ming Console’s monitor operations. Check the input wiring with the
Slaves input indicators, the Programming Console’s I/O monitoring, or
the Programming Console’s multiple address monitoring.
3. Test Run
Use a Programming Console to set the SRM1 to RUN or MONITOR mode
and check that the “RUN” indicator lights.
4. Program Input
a) Use the Programming Console, SYSMAC-CPT, or SYSMAC Support
Software (SSS) to write the program.
b) Check the sequence of operation.
Note When using the SYSMAC-CPT Support Software, set the PC model
to “SRM1.” When using the SYSMAC Support Software, set the PC
model to “CQM1.”
5. Debugging
Correct any programming errors that are detected.
5-1-3 Flash Memory Precautions
The SRM1 uses the flash memory to hold the contents of the user program
memory, the read-only DM area (DM 6144 through DM 6599), and PC Setup
(DM 6600 through DM 6655). Observe the following precautions to protect the
flash memory and ensure proper operation.
1, 2, 3... 1. Perform either one of the following to write the above contents onto the flash
memory.
a) Switch the SRM1 to RUN or MONITOR mode.
b) Restart the power supply to the SRM1.
Note If the power is turned off without changing the mode after making
changes in the above areas using a Peripheral Device, the changes
will not be written to flash memory. Although the data in these areas is
backed up by a lithium battery, the changes will be lost if the battery
fails or is removed because the program in the flash memory will be
automatically read into the user program memory. The standard ser-
vice life of the lithium battery is ten years minimum under an ambient
temperature of 25°C.
2. When the SRM1 is operated for the first time after changing the program
memory, the read-only DM area (DM 6144 through DM 6599), or PC Setup
(DM 6600 through DM 6655), it will take about 850 ms longer than usual be-
fore the SRM1 starts. Be sure to take this one-time startup delay into ac-
count.
