Module IMI220-432A001/B001 is a double module (occupies two card slots) consisting of a main process section and by a video section.
Main process section activities can be sub-divided in two types:
- basic software run (operating system);
- user-written program run.
On the module there is a HCMOS, 32-bit microprocessor performing execution of an elementary instruction on a variable (LD, AND, OR, ST) in 240 nanoseconds, while elementary instructions on registers are executed in 95 nanoseconds.
The video section can control a monochrome LCD display (VGA) in graphical mode, therefore it is possible to display graphs and synoptic drawings; it is also possible to connect a local matrix keyboard locale (lines x columns) provided with max 88 keys and 64 led the keyboard may be either a 400 series matrix keyboard or a custom keyboard made in accordance with specifications from Moog.
On the same rack there cannot be mounted more than one module IMI220-432A001/B001/D001, nor any other main processor module.
Maximum allowed length for display cable is 3 m.
Maximum allowed length for matrix keyboard cable is 3 m.
Module IMI220-432A001 CANNOT be placed beyond card slot # 16.

Main Processor Section
- Red LED (Halt): if on, indicates a hardware problem (processor in HALT);
- Green LED (Run, Prg): if the module is in RUN this led is always on; when programming the PLC this led blinks at a frequency of about 1.6 Hz; if the PLC is not operating (BOSS) it led blinks at a frequency of about 1 Hz;
- 25 pin connector: is used to connect Series 400 PLC to the personal computer used for la programming or for remote control;
- USB connector: used to connect the Series 400 PLC to the personal computer used for the programming or remote control.
- 9 pin connector: is used to connect Series 400 PLC to intelligent graphical terminals;
Video section
- 34 pin connector: is used to connect an LCD VGA B/W display;
- 25 pin connector: is used to connect the matrix keyboard.
