Data Exchange with the CPU Unit Section 2-5
2-5-2 Data Exchange Settings
Data Format
The format used to store data during data exchange between the CPU Unit
and Temperature Control Unit in the words allocated to the Temperature Con-
trol Unit in the CIO and DM Areas must be set in advance. The data format is
set using pin 3 on the DIP switch for function settings. It can be set to either 4-
digit BCD or 16-bit binary (4-digit hexadecimal). The same format is used for
user-set and system-set data and for the Special I/O Areas in both the CIO
and DM Area.
Unit Number
The words allocated to the Temperature Control Unit in the CIO and DM
Areas are determined by the unit number set for the Temperature Control Unit
as a Special I/O Unit.
Note 1. If two or more Special I/O Units are assigned the same unit number, an
“UNIT No. DPL ERR” error (in the Programming Console) will be generat-
ed (A40113 will turn ON) and the PLC will not operate.
2. Each Temperature Control Unit is allocated the words for two unit numbers.
Do not use assign the unit number after one assigned to a Temperature
Control Unit to any other Unit. For example, if unit number 5 is allocated to
a Temperature Control Unit, the words for both unit number 5 and 6 will be
allocated to it, and unit number 6 must not be assigned to any other Unit.
