3-6 SB3000 Drive Configuration and Programming
3.2 Rail I/O Port Registers (Registers 0-23)
The Rail I/O Port 0 and Port 1 views are used to assign variable names to the rail ports
on the PMI. If you have no hardware attached to these ports, do not configure these
registers. All of the Rail data for PMI A and PMI B is combined into one section of the
dual port memory. Refer to table 3.3. Note that the usage of each register is a function
of the type of Rail that is configured. After a STOP ALL, outputs are reset to zero and
inputs continue to be updated.
The appropriate variable configuration screen will be displayed based on the hardware
that you have specified to be connected to the port.
The following types of hardware can be connected to these ports. The instruction
manual for the hardware listed is shown in parenthesis.
Each Rail I/O port has a set of bits that display any errors that may occur and a fault
counter that is incremented each time a bad communication check bit is detected. The
user’s application program must regularly examine these bits and registers. Refer to
tables 3.4, 3.5, and 3.6. The check bit fault counter is reset to zero when a warning
reset signal (register 100/1100, bit 9) is generated through the UDC module from the
application program.
Table on the following page lists the Rail I/O port registers.
