Range selection and software configuration

[Range selection switch position]

The following table shows how to set the range of the SM231 8AI module with the DIP switch. Switches 1, 2 and 3 can select the analog input range. All inputs are set to the same analog input range. In the following table, ON means connection and OFF means no connection. It is important to note that unused DIP switches SW4 ~ SW6 must be set to the OFF position.

Single polarity			Full scale input	Resolution
SW1	SW2	SW3
ON	OFF	ON	0-10V	300μV
	ON	OFF	0 - 5V	150μV
Bipolar			Full scale input	Resolution
SW1	SW2	SW3
OFF	OFF	ON	± 5V	150μV
	ON	OFF	± 2.5 V	75μV

 

[Software Configuration]

For the SM231 8AI× 16-bit analog input module, its reading is in VW, not AIW, the relative position of the module is different, the corresponding address is different. The address calculation formula is as follows:

X (VWx) = slot number × 64 + input channel number × 2

The slot number corresponds to the module's installation location, with the first extension slot next to the CPU being 0, the second extension slot being 1, and so on. There are 8 input channels, from A to G, and the corresponding numbers are 0 to 7.

 

VWxx	Channel 0	Channel 1	Channel 2	Channel 3	Channel 4	Channel 5	Channel 6	Channel 7
Slot 0	VW0	VW2	VW4	VW6	VW8	VW10	VW12	VW14
Slot 1	VW64	VW66	VW68	VW70	VW72	VW74	VW76	VW78
Slot 2	VW128	VW130	VW132	VW134	VW136	VW138	VW140	VW142
Slot 3	VW192	VW194	VW196	VW198	VW200	VW202	VW204	VW206
Slot 4	VW256	VW258	VW260	VW262	VW264	VW266	VW268	VW270
Slot 5	VW320	VW322	VW324	VW326	VW328	VW330	VW332	VW334
Slot 6	VW384	VW386	VW388	VW390	VW392	VW394	VW396	VW398

Note:  Because the offset address of TD2X text display is also in VW0, so If you need to use Td2X text display in your system, please don't put the EM231 8AI×TC module in slot 0, or the TD2X will not work normally. Siemens TD200 text displayer is same as TD2X.
