Communication, Counter and Pulse
SECTION 4
Ladder Diagram The following table shows the instruction operations related to interrupt input
Programming (counter mode) control.
Instruction Control Operation
Refresh incrementing
counter SV
Refreshes the counter’s SV and starts the
incrementing count.
Refresh decrementing
counter SV
Refreshes the counter’s SV and starts the
decrementing count.
Mask all interrupts Prohibits all interrupts, including interrupt
inputs, interval timer interrupts, high-
speed counters, etc.
(@)INT(89)
Unmask all interrupts Permits all interrupts, including interrupt
inputs, interval timer interrupts, high-
speed counters, etc.
(@)INI(61) Change PV Changes the counter’s PV.
(@)PRV(62) Read PV Reads the counter’s PV.
The functions related to input interrupts (counter mode) are executed accord-
ing to the data areas shown in the following table.
Word Bits Name Contents
240 00 to 15 SV area for input interrupt (counter mode) 0
241 00 to 15 SV area for input interrupt (counter mode) 1
242 00 to 15 SV area for input interrupt (counter mode) 2
243 00 to 15 SV area for input interrupt (counter mode) 3
Stores the
counter’s set
value(SV) .
244 00 to 15 PV area for input interrupt (counter mode) 0
245 00 to 15 PV area for input interrupt (counter mode) 1
246 00 to 15 PV area for input interrupt (counter mode) 2
247 00 to 15 PV area for input interrupt (counter mode) 3
Stores the
counter’s
present value
(PV).
Refresh Incrementing Counter SV / Refresh Decrementing Counter SV
These functions store the counter’s set values in data areas and refresh them
by means of INT(89). In this way, they start the count operation for interrupt
inputs (counter mode) and they permit interrupts.
Storing Set Values in Data Areas
The counter’s set values are stored in words 240, 241, 242, and 243.
SR 240 SV for interrupt input (count mode) 0: 0000 to FFFF
SR 241 SV for interrupt input (count mode) 1: 0000 to FFFF
SR 242 SV for interrupt input (count mode) 2: 0000 to FFFF
SR 243 SV for interrupt input (count mode) 3: 0000 to FFFF
