D-5 Memory switches
D-6 Special memory list
■ Temporary memory
Attribute R: Read, W: Write
■ Communication data memory
TM00 Used for arithmetic operations (DIV/MUL) Attribute: R/W
TM01 Used for arithmetic operations (DIV) Attribute: R/W
TM02 to TM27 Can be used by user Attribute: R/W
TM28 Stores scan time beyond set value while constant scan Attribute: R
time operation is performed.
TM29 Stores set value of constant scan time operation Attribute: R/W
TM30 Stores CTC0 value when INT3 interruption is given. Attribute: R
TM31 Stores measured scan time (mean value of Attribute: R
every 10 scans).
bit0 Cancels error when power is ON. 1: Retains
0: Clears them and starts
operation.
bit1 Cancels error message "MEMORY ERASED" when 1: Memory error
value in data memory/counter or latch setting is erased. 0: Clears error and
continues operation.
bit2 Uses latch function of internal utility relays 1000 1: Yes 0: No
through 1915.
bit3 Uses latch function of internal utility relays 3000 1: Yes 0: No
through 3915.
bit4 Uses latch function of internal utility relays 4000 1: Yes 0: No
through 4915.
bit5 Uses latch function of internal utility relays 5000 1: Yes 0: No
through 5915.
bit6 Uses latch function of internal utility relays 6000 1: Yes 0: No
through 6915.
bit9 Clears DM0000 to DM0999 at power-on. 1: Clears 0: Retains
bit10 Clears DM1000 to DM1899 at power-on. 1: Clears 0: Retains
bit11 Switches between 24- and 16-bit comparators 1: 24-bit 0: 16-bit
for CTH0.
bit12 Switches between 24- and 16-bit comparators 1: 24-bit 0: 16-bit
for CTH1.
bit13 Clears values of counter, CTH, and CTC. 1: Clears 0: Retains
bit14 Write-protects program in KV PLC. 1: Yes 0: No
bit15 Read-protects program in KV PLC. 1: Yes 0: No
DM1000 to DM1099 Stores received text (PORT A)
DM1100 to DM1199 Stores text to be transmitted (PORT A)
DM1200 to DM1299 Stores received text (PORT B)
DM1300 to DM1399 Stores text to be transmitted (PORT B)
