(master).
Two areas are used in PLC memory by the E5@C, 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. The download
area is used to write the set point, alarm values, and other values to the E5@C.
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 Controller is connected to the same communications line, set the starting address to
the same value for all of them. The E5@C Controller with communications unit number 0 will use the words
that start from the specified starting address, the E5@C Controller with unit number 1 will use the words that
start from the specified starting address plus 30 words, and the E5@C Controller with unit number 2 will use
the words that start from the specified starting address plus 60 words
