E5@C Digital Temperature Controllers Communications Manual (H175)
Communications Setting Level
Display condition: The Protocol Setting parameter must be set to fins, mcp4, or fxp4.
Note: 1 The First Address Upper Word and First Address Lower Word parameters together specify the first
address.
Example: (1) If the first address of the PLC is 123456, set the First Address Upper Word parameter to
12 and the First Address Lower Word parameter to 3456 in the E5@C.
(2) If you use an area labeled with “*1,” convert the first address of the PLC (hexadecimal) to
a decimal number and set the decimal value in the E5@C.
If the first address of the PLC is 12345, set the First Address Upper Word parameter to 7
and the First Address Lower Word parameter to 4565 in the E5@C.
2 Set the same first address in all of the E5@C Controllers (e.g., set the same value as the value that is set
for the E5@C with communications unit number 0).
