3.2 Flex I/O Port Registers (Registers 0-23)
The Flex I/O Port 0 view is used to assign variable names and configure the registers
used for the Flex I/O port on the PMI. If you have no hardware attached to this port,
do not configure these registers. All of the Flex I/O data for PMI A and PMI B is
combined into one section of the dual port memory. The appropriate variable
configuration screen will be displayed based on the hardware that you have specified
is connected to the port.
Note that the use of each register is a function of the type of Flex I/O module
configured. After a Stop All, outputs are reset to zero and inputs continue to be
updated.
The Flex I/O interface is designed to handle up to three Flex I/O modules. Registers
0/12 and 1/13 are reserved for digital I/O. Registers 2/14 to 9/21 can be used for a
digital I/O module or an analog module. Registers 10/22 and 11/23 are used for Flex
I/O status and error codes.
Table 3.3 lists the UDC registers reserved for Flex I/O.
