The sizes can be adjusted through the PrmData. The length is modified in steps of 8 bytes.
Example:
If it is desired to increase the size of the input data, other sizes must be reduced to compensate.
If we have 20 x 4 channel KL3314 thermocouples, then in compact mapping we find 20 Bus Terminals * 4 channels *
2 bytes per channel = 20 * 4 * 2 = 160 bytes
160 bytes is larger than the 128 byte default figure - settings must therefore be modified.
Set PrmData byte 12 bits 4-7 to 15 dec or 0xF hex, set byte for 37 to 160 (input data) and byte 38 to 96 (output data).
