3. Input Type Setting PART 1 AD268 3. Input Type Setting The AD268 supports multiple input ranges, ±5V, ±10V, 0 to 5V, 0 to 10V, 1 to 5V, 0 to 20mA, or 4 to 20mA. The input range is selected by jumper plug setting and the parameter writing by the T2 program. The general flow for setting the input type is as follows. (1) Set the jumper plugs to select voltage input or current input. (2) Mount the AD268 onto the T2 rack. (3) Turn on power to the T2 system. (4) Execute I/O allocation. (5) Progra

PART 1 AD268 3. Input Type Setting 3.2 Parameter setting by software The input range of the AD268 is specified by writing the following parameter data into the AD268's buffer memory. To access the buffer memory, T2 user program (READ and WRITE instructions) is required. When the parameter is set to the AD268, it is saved in the AD268's built-in EEPROM. Therefore, once the input type parameter is set, there is no need to execute the input type setting operation. T2 CPU AD268 Buffer memory WRIT

4. Wiring PART 1 AD268 4.3 Wiring precautions (1) Use shielded twisted-pair cables for analog input signal lines and wire them in shortest distance. Connect the cable shield to ground in shortest distance for EMC conformity. Normally the grounding method (a) is recommended. However, depending on the condition, method (b) or (c) may be useful for stable operation.

PART 1 AD268 5. I/O Allocation and Programming 5. I/O Allocation and Programming 5.1 Allocation to the T2 registers The I/O type of the AD268 is "X 8W". When the automatic I/O allocation operation is performed with a AD268 mounted on the rack, the AD268 is allocated as "X 8W". The AD268 occupies the 8 consecutive input (XW) registers of the T2. In this manual, these assigned I/O registers are expressed as XW(n), XW(n+1), ... XW(n+7). The following figure shows an example of I/O allocation wi
