Description
2DI, 24 V, 3 ms:
1. Digital I/O module with a data width of
2 bits. Since the analog input modules
already occupy the first 8 words of the input
process image, the 2 bits occupy the lowest-
value bits of the 8th word.
2AO, 4 – 20 mA:
1. Analog output module with a data width of
2 words. This module occupies the first 2
words in the output process image.
4DI, 24 V:
2. Digital input module with a data width of 4
bits. These are added to the 2 bits of the 750-
400 and stored in the 8th word of the input
process image.
%QX4.0
4DO, 24 V:
1. Digital output module with a data width of
%QX4.1
4 bits. Since the analog output module
%QX4.2
already occupies the first 4 words of the
output process image, the 4 bits occupy the
%QX4.3
lowest-value bits of the 4th word.
2AI, 4 – 20 mA:
1. Analog input module with a data width of
2 words. This module occupies the first 2
words in the input process image.
RS232, C 9600/8/N/1:
The serial interface module is an analog input
and output module, which displays 2 words
apiece both in the input process image as
well as in the output process image.
4AI, 0 – 10 V S.E:
2. Analog input module with a data width of
4 words. Since the 750-454 and 750-650
analog input and output modules already
occupy the first 4 words of the input process
image, the 4 words of this I/O module are
added behind the others.
