1.2 Features
1) iS7 PLC option card is compact type which is integrated the function of CPU, Input and output,
and communication function. PLC option card has features of below described.
(1) High speed processing
High speed processing of 0.1
μ
s/Step
(2) Various built-in functions
PLC option card can perform the various system by just using the one option card.
•
Fast processing applications
- Pulse catch: Allows the option card to read a pulse which has a width as small as 10
㎲
.
- External interrupt: Using in various applications with built-in 6 interrupt input that
high-priority event which requires immediate responses.
•
The input filter function helps to reduce the possibility of false input conditions from
external noise, such as signal chattering. The filter time can be programmed from 0 to
1000ms.
•
Using RS-232C and RS-485 built-in port, the option card can connect with external
devices, such as personal computers or monitoring devices and communicate 1:N
with external device.
•
Using built-in PID control function, PID control system can be constructed without
using separate PID module.
(3) Battery-less
The user’s program can be saved permanently without battery, because it is stored in
EEPROM.
(4) When program is edited during processing, it is stored in EEPROM automatically.
(5) It supports the Master function at Modbus-RTU protocol.
(6) It can easily do On/Off of the system, using RUN/STOP switch.
(7) it can save the program permanently in EEPROM by easy editing with KGLWIN.
(8) Strong self-diagnostic function
It can detect the cause of errors with more detailed error codes.
(9) It can prevent unintentional reading and writing, using password.
(10) Various program execution functions
External and internal interrupt program as well as scan program can be executed by
setting the execution condition. Therefore, user can set various program execution
modes.
