Programmable Logic Controller ( PLC )
|
| |
|
Specifications: |
| 1. |
32 Basic sequential
commands (Including STL/RET) and 79 application commands (127 including
the 32-bit commands). |
| |
|
| 2. |
EEPROM is utilized for program
storage. The capacity of 4K models is 3792 STEPS. |
| |
|
| 3.
|
Extension of the input and
output point could both reach 128 points, respectively. |
| |
|
| 4. |
Internal auxiliary relay
M0~M1279. 16-bit Timer (T0~T127) and counter (C0~C127) each possesses
128 of them and each of them could be utilized independently. |
| |
|
| 5. |
Data register D0~D599 and
D1000~D1143 with 192 power retaining zones in the 4k model. |
| |
|
| 6. |
Pointers utilize P0~P63 to
support the calling of subordinate programs and to execute 4 external
interruptions (I001~I301). |
| |
|
| 7. |
There are 13 32-bit high-speed
counters (C235~C254). The one-phase high-speed counter with 5KHz. The
two-phase (A and B) high-speed counter with (2KHz). |
| |
|
| 8. |
One PWM output on Y1. |
| |
|
| 9. |
Two plus output on Y0, Y1 (PLSY).
The single-axis PLSY has a 10KHz output and the double-axis is 5KHz
output.
|
| 10. |
The EX model possesses the A/D
(4-CH, 10 bit) and D/A (2-CH, 8 bit) functions. |
|
Self-Examination and Protection |
| 1.
|
Examine on the
exceeding system execution time, illegitimate commands, error usage of
the operands, and program grammar. |
| |
|
| 2.
|
Self-examination on the hard
drive: CPU/ROM/RAM and the Peripherals. |
| |
|
| 3.
|
Users could provide 4 ASCII
words to serve as the MPU password, and the password could be used to
prevent arbitrary read-out and destruction of the programs would be
provided to remove the original MPU password (however, it will entirely
delete all the programs within the MPU). |
|
|
Built-in Interface of RS-232 |
| 1.
|
Could directly with
handheld programming panel (HPP). (Connect with DVPACAB115) |
| |
|
| 2.
|
Could directly with PC. (Connect
with DVPACAB215) |
| |
|
| 3.
|
Could directly with human
machine interface (HMI). (Connect with VPACAB315) |
|
Built-in Interface of RS-485 |
| 1.
|
Could connect with
PC (the PC terminal should be equipped with a RS-485 « RS-232
converter). |
| |
|
| 2.
|
Could connect with the
human-machine interface, HMI. Could also connect with equipment
possesses the ASCII communication control mode. |
| |
|
| 3.
|
The PLC could serve as the
MASTER/SLAVE terminal that possesses the MODBUS interface and thus could
drive up the specific convenient commands (which support the ASCII/RTU
modes), MODBUS and MODWR; moreover, it could connect directly with
Delta’s VFD-M/P/B/S/L and V Series Inverter. Furthermore, there are
specific commands, FWD/REV/RDST/RESTEF/STOP, designed especially for
Delta’s VFD-A Series Inverter. |
| |
|
| 4. |
PLC will automatically handle
any communication abnormalities, ASCII words and the conversion and
checksum of the HEX numerical values. |
