Functions of PLCS
The functions of PLCS is registered with the PLCS server engineering tool.
Table 3.3 shows the basic specification of tags supported by the PLC server.

Item
Specifications
Tag Count
Digital : 4096 tags/second
Analog : 200 tags/second - 1024 tags/5 seconds Total 4096 tags
However, Max.990 tags/PLC(when 1 tag is counted as 1 word)
Tag Type
Digital : PB2p/PB4p/PB8p(only for PLC)
PB3e(only for L1)
Analog : INDp/PFIp/SETp (only for PLC)
DB1p/DB8p(PLC,L1 common use)
INDe/TTLe/PIDe/SPIe/MAe/RSe(only for L1)
PolyLine
Information
Polyline information used for linearization conversion is included as parameter tags.
Polyline count: 256 point(Point Count : 11 points/poly line)
Input Signal Type
Only instantaneous values are used as input signals for analog tags.
Count value ( -32768 to 32767, integer/BCD)
Linearize value (% value, real number)
Engineering unit value (real number)
Alarm process
(with alarm
suppress function)
Digital tags
DI1-DI8 error
Analog tags
Pv sensor high /low limit alarm
PV over limit/high limit/low limit/under limit alarm
PV process error
PV rate-of-change alarm
Positive deviation/negative deviation alarm
Tag Write
Digital
Operations(latch, momentary, etc.) corresponding to
a pushbutton command (RFO) are implemented by the PLC
application.Errors such as network down during momentary are
handled by the PLC application.
Analog
After a SETp tag SV value write is deleted, the FBSV value ie updated by the PLC
application.
Operation Processes
Analog tags
Liniarization conversion(uses polyline information) Power
factor conversion, phase angle conversion(PFIp/PFIs tags only)
Digital tags
Input/output signals inversion
Operation Record
For digital tags, operation record can be enabled or disabled for signal changes.(Input signal
operation record, output signal operation record)
FI
Signal Change
Buzzer Output
For digital tags, buzzer output can be enabled or disabled for FI signal changes.
