Memory Clear
The memory clear operation clears all memory areas except the I/O comments
and UM Allocation information.
The key sequence for a partial memory clear is shown below.
The Programming Console will display the following screens:
00000
00000
00000
00000MEMORY CLR?
HR CNT DM
00000MEMORY CLR
END HR CNT DM
Note When the write-protect switch (pin 1 of the CPU’s DIP switch) is set to ON the UM
area (from DM 6144 through the ladder program) will not be cleared. Other data
areas, such as HR, AR, CNT, and DM from DM 0000 to DM 6143 will be cleared.
4-6-4 Registering the I/O Table
The I/O Table Registration operation records the types of I/O Units controlled by
the PC and the Rack locations of the I/O Units. It also clears all I/O bits.
It is not absolutely necessary to register the I/O table with the C200HS. When the
I/O table has not been registered, the PC will operate according to the I/O Units
mounted when power is applied. The I/O verification/setting error will not occur.
