(NUMI)
Numeric inputs to a PAC schematic from a PLC can be visualized as shown in
Figure 7. Numeric input (NUMI) PAC blocks receive a numeric value sent to
the drive from the remote device specified by the node, channel, and sub
channel defined for that block. The node number for a single PLC gateway is
typically 200.
The channel number here has the same meaning as the numeric outputs, except
that the leading digit is always 0. The SmartMUX board only supports
Numeric block transfers to slot 0 and group 0. Thus:
LAN CHANNEL 030 = RACK 3, GROUP 0
The PAC block’s sub channel number will be in decimal, and will normally be
between 0 and 63. This number represents the location of the numeric input
data in the Block Transfer Write data file. Up to 64 values may be processed
in one Block Transfer operation. Only one BTW can be used for each
Gateway.
