Constant
K Decimal
K-32,768 ~ K32,767 (16-bit operation),
K-2,147,483,648 ~ K2,147,483,647 (32-bit
operation)
H Hexadecimal
H0000 ~ HFFFF (16-bit operation),
H00000000 ~HFFFFFFFF (32-bit operation)
Serial Ports
COM1: built-in USB (Slave)
COM2: built-in RS-485 (Master/Slave)
COM3: built-in RS-485 (Master/Slave)
Ethernet: built-in Ethernet (Please refer to Appendix
B for more information.)
COM1 is typically the programming port.
Real Time Clock
Year, Month, Day, Week, Hours, Minutes, Seconds;
When the power is off, this function can still go on
for about 1 week.
Special I/O Modules
Right side: Up to 8 I/O modules can be connected.
Left side: Up to 8 high-speed I/O modules can be
connected.
Notes:
1. Non-latched area cannot be modified.
2. Latched area cannot be modified.
3. COM2: built-in RS485 port. COM3: built-in RS485 port.
4. The PLC occupies 16 input points (X0~X17) and 16 output points (Y0~Y17). The extension
input point starts from X20 and extension output point from Y20.
5. If an SE series MPU is connected to a right-side special module, and M1183 is Off, the data
registers can be used. Each connected special module occupies ten data registers.
6. If an SE series MPU is connected to a left-side special module, and M1182 is Off, the data
registers can be used. Each connected special module occupies ten data registers.
