IB[N] - Input Bits Array
Purpose:
Provides read access to digital input bits.
IB[N] reports the status of the corresponding input bits, according to the definition in IP.
If IB[N] is “1”, the corresponding Nth bit in IP is logically active.
Use the IB[N] command to reference general purpose inputs, limit switches and other
indications (such as Stop, Begin or Enable) individually.
IB[N] may be more convenient than IP for program decisions and branching. However, it
is not appropriate for the synchronized reading of several input bits. If a synchronized
reading of several digital inputs is desired, use the IP command.
Refer to the IP command for more details about the role of each bit.
Attributes: Type: Status report, Integer
Source: Program, RS-232, CANopen
Restrictions: None
Index range: [0…31]
Unit modes: All
IB[N] reports according to the polarity programmed for the relevant digital input
by the IL[N] command.
