Component Description
To assign the analog input modes of AI1~AI2. When the power is turned from OFF to ON, the default value is H00.
When the power is turned from OFF to ON, the default value is 10.
The available range is 1~32,767, otherwise it is equivalent to 10.

Identication code: VS-3A = K203 (can use the FROM instruction to check whether the place is this module or not)
The version number of this module. (the content value XX indicates Ver. X.X)
Converted digital value of AI1 (the average times is designated by BFM #1).
Converted digital value of AI2 (the average times is designated by BFM #2).
To assign the analog output mode of AO1. When the power is turned from OFF to ON, the default value is H0.
To assign the holding mode of AO1. When the power is turned from OFF to ON, the default value is H0.
To set the average times of AI2.
To set the average times of AI1.
#21
When the power is turned from OFF to ON, the default value is 0.
The digital set value of AO1.
BFM#0 To appoint the modes of analog inputs: (the sliding switch should also consistent with the modes)
Example: If the BFM #0 of a VS-3A is set to be H20, then
AI1: For –10V~+10V voltage input, that will be converted to the value –32,000~+32,000 at this mode.
AI2: For 4mA~20mA current input, that will be converted to the value 0~+16,000 at this mode.

If the value in the nibble = 0, the channel will keep the last output, even PLC
is STOP.
If the value in the nibble ≠ 0, the channel will change its digital set value = 0
at STOP.
BFM#20 To appoint the mode of analog output:
Example: If the BFM #20 of a VS-3A is set to be H2, then
AO1: For 4mA~20mA current output, that will use the digital set value 0~+32,000 at this mode.
