Function
The term “bank” refers to groups of eight digital I/O points. A 32-channel Pamux board with a B4
brain board has four banks. It is faster to read a bank all at once than to read each point individually.
Note that channel 0 corresponds to the least significant bit. For example, if you read a bank with
channels 0, 3, and 4 on and all other channels off, the returned value would be 19 hex (11001 binary,
or 25 decimal).

Parameter
Configures a bank of digital I/O points as
either inputs or outputs. A “1” in the
mask indicates an output. Use Pamux-
DigBankConfig for configuring between
8 and 32 points,
PamuxDigBank16Config for 16 points, or
PamuxDigBank32Config for 32 points.
The Byte Qty parameter in PamuxDig-
BankConfig indicates how many banks
to configure (Byte Qty = 4 for 32 points).
Reads inputs and outputs and places
the result in pData. Use PamuxDig-
BankRead for reading eight points,
PamuxDigBank16Read for 16 points, or
PamuxDigBank32Read for 32 points.
