Initial System Checks

Check the following items after setting up and wiring the CPM2B-S, but before
performing a test run.
Power supply and
I/O connections
Connecting cables Are the cables all connected correctly and locked?
Always clear memory before beginning to program the CPM2B-S. Although
memory is cleared before the CPU Board is shipped, the contents of the DM,
HR, AR, and counter areas may change in transit.
See 1-3-3 Operating Mode at Startup to determine what mode the CPM2B-S
will enter when the power is turned on.

Flash Memory Precautions

Observe the following precautions to protect the flash memory and ensure
proper operation.
1,2,3... 1. If changes are made in the read-only DM area (DM 6144 through DM
6599) or PC Setup (DM 6600 through DM 6655), the PC's operating mode
must be changed to write the new contents to flash memory. If backup bat-
tery is replaced before the changes are written to flash memory, the chang-
es will be lost.
The changes can be saved by switching the CPM2B-S to RUN or MONI-
TOR mode or turning the CPM2B-S OFF and then ON again.
2. When contents of the program, read-only DM (DM 6144 through DM
6599), or PC Setup (DM 6600 through DM 6655) have been changed, star-
tup processing will take up to 1,200 ms longer than usual. Be sure to take
this one-time startup delay into account if it may affect operations.
3. If one of the following three operations is performed in MONITOR or RUN
mode, the CPM2B-S's cycle time will be extended by up to 1,200 ms and
interrupts will be disabled while the program or PC Setup is being overwrit-
ten.
• Program changes with the online edit operation
• Changes to the read-only DM area (DM 6144 through DM 6599)
• Changes to the PC Setup (DM 6600 through DM 6655)
A "SCAN TIME OVER" error won't occur during these operations. Be sure
to take this delay in the CPM2B-S's I/O response times into account when
performing online editing.
1,2,3... 1. Power Supply Application
a) Check the CPM2B-S's power supply voltage and terminal connec-
b) Check the I/O devices' power supply voltage and terminal connec-
c) Turn on the power supply and check that the "PWR" indicator lights.
d) Use a Programming Device to set the CPM2B-S to PROGRAM mode.
Item
Is the wiring correct?
Are the terminals securely tightened?
Are there any shorts between crimp terminals or wires?
