Figure C-11 AI Parameters in Byte 12 or 17 of DS130
The third byte (byte 13 or byte 18) of the channel-specific parameters is al-
ways assigned the value 00
H
for input modules.
The purpose of bits 0 to 5 in bytes 11 and 16 of data record 130 for analog
output modules is indicated in Table C-12.
Bit 6 is always assigned the value “0”.
Bit 7 specifies the number format:
Bit 7 = “0”: S7 format
Bit 7 = “1”: S5 format
