3.1 Introduction
All external connections to the Digital I/O option card are made using the 24-pin connector.
The required Weidmüller Minimate B2L 3.5/24 mating connector is supplied.
The digital inputs and outputs are described in the following sections.
3.1.1 Slot selection and input / output numbering
The MotiFlex e100 implements a system of I/O 'banks', with each bank allowing up to 32
inputs and outputs. The I/O available as standard on the MotiFlex e100 always resides in
bank 0. The I/O available on option cards resides in bank 1 if the card is inserted in slot 1, or
bank 2 if the card is inserted in slot 2.
The numbering of bank 1 (slot 1) inputs and outputs always starts at 32, since 0-31 are
reserved by bank 0 (even though only DIN0-DIN2 and DOUT0-DOUT1 are used by a
standard MotiFlex e100).
The numbering of bank 2 (slot 2) inputs and outputs always starts at 64, since 0-31 are taken
by bank 0, and 32-63 are taken by bank 1.
This numbering system is summarized in the following table, and in Figures 3-1 and 3-2.
Bank/Slot
0 Standard drive,
connector X3
1 Option card, top slot
2 Option card, bottom slot
The same numbering system is used when referring to the I/O using the Mint INX and OUTX
keywords; for example DOUT32 is referred to as OUTX(32). See the Mint help file for
details.
