M16..M1 Mode bits. A low mode bit selects ±10V and a high mode bit selects ±20mA.

F15..F13 Filter bits. Input digital filter time constant codes for analog input modules.

A16 Adaptive filter enable bit for analog input modules.

F13 through F15 and A16 are used in place of M13 through M16 by modules with analog

inputs.

S16..S1 Scale bits. A low scale bit selects ±10V or ±20mA for the corresponding channel. A

high scale bit selects ±5V or 4-20mA. S13 through S16 are not used by modules with

analog inputs.

Each analog input has a single pole 345Hz (461uS) cutoff high frequency noise filter. In addition a

second digital filter may be specified with the following time constants.
