Basic information of SIMATIC S7-200 Smart Signal board
| Model | Specification | Description |
| SB DT04 | 2DI/2DO transistor output | It provides additional digital I/O extensions, and support 2 digital inputs and 2 digital transistor outputs. |
| SB AE01 | 1AI | It provides additional analog I / O expansion, and support 1Analog input , the precision is 12 bits |
| SB AQ01 | 1AO | It provides additional analogue I/O extension, and support 1 analogue output, with a precision 12 bits. |
| SB CM01 | RS232/RS485 | It provides additional RS232 or RS485 serial communication interface, the conversion can be realized via simple configuration in the software. |
| SB BA01 | Battery module | It supports the generic CR1025 cell (battery), which can drive the clock for about 1 year. |
S7-200 Smart Signal board configuration
When the standard CPU module is selected in the system block, the aforementioned
four signal boards will display the SB options:
When SB DT04 is selected, the system can automatically distribute I7.0 and Q7.0 as the beginning of the I/O image area
When SB AE01 is selected, the system can automatically allocates AIW12 as I / O image area
When SB AQ01 is selected, the system can automatically allocates AQW12 as the I/O image area
When SB CM01is selected, it can be done via selecting the RS232 or RS485 in the port type setting box.
When SB BA01 is selected, the low power consumption alarm can be initialized or the power consumption state can be monitored via I7.0.
