Communications Setting Level
Display condition: The Protocol Setting parameter must be set to fins or mcp4
The Protocol Setting parameter must be set to cmp and the Communications Unit No. parameter must
be set to 0 (master).
Two areas are used in PLC memory by the E5@C-T, an upload area and a download area. The upload
area is used to monitor the process value, status, and other information from the E5@C-T. The down-
load area is used to write the fixed SP, segment SPs, segment times, alarm values, and other values to
the E5@C-T.
The Response Flag, Communications Status, Request Flag, and Operation Command Code all have
special functions that cannot be changed. Refer to the following sections for application methods.
Request Flag: 6-3-1 Controlling Programless Communications with the Request Flag
Response Flag: 6-3-2 Response Flag
Operation Command Code: 6-3-4 Operation Command Codes
Communications Status: 6-3-5 Confirming Operation of Programless Communications
The portion of PLC memory to use is set with the Area, First Address Upper Word, and First Address
Lower Word parameters.
Note: If more than one E5@C-T Controller is connected to the same communications line, set the starting address
to the same value for all of them. The E5
@C-T Controller with communications unit number 0 will use the
words that start from the specified starting address, the E5
@C-T Controller with unit number 1 will use the
words that start from the specified starting address plus 70 words, and the E5@C-T Controller with unit
number 2 will use the words that start from the specified starting address plus 140 words
