2. Programming Concepts Notes: 1. Non-latched area cannot be modified 2. Latched area cannot be modified 3. COM1: built-in RS232 port. COM2: built-in RS485 port. COM3: built-in RS485 port. 4. When input points(X) are expanded to 256 points, only 16 output points(Y) are applicable. Also, when ouput points(Y) are expanded to 256 points, only 16 input points(X) are applicable. 5. This area is applicable only when the ES2/EX2 MPU is connected with special I/O modules. Every special I/O module occupies 10 points. 6. PLC with firmware version 2.00 or later support the function of keeping track of the current even after the power is off.
When the power is off, this function can go on for about 1 week. 7. PLC with firmware version 2.00 or later versions support the function of file register. Refer to the instructions MEMR/MEMW for more details on operation. 8. Ethernet: this function is only available for DVP-EX2-E series PLC. 9. This function is available for ES2 and EX2 series with firmware V3.46 or later and for EX2-E series with firmware V1.08 or later.
