Node_Name
Block_Number
PCCC_Type
Address
Length
Note the number of bytes per PCCC_Type:
SINT, INT = 2 bytes, REAL, FLOAT = 4 bytes, BOOL, BIT, FLAG = 8 bits per byte
Each PLC file is 2000 bytes long and therefore the address values will range from zero
to a maximum value as indicated. The start address is specified in increments of the
basic data type specified under PCCC_Type.
The message buffers in the ControlNet card are each 498 bytes long and only one
message buffer can be allocated to a Map Descriptor. The Map Descriptor lengths are
therefore limited to maximum values as indicated when taking the data type byte lengths
into account.
