6. RKC COMMUNICATION
IMS01T28-E4
6-4
4. ENQ
The ENQ is the transmission control character that indicates the end of the polling sequence. The host
computer then must wait for a response from the SRZ.
(3) Data sent from the SRZ
If the polling sequence is received correctly, the SRZ sends data in the following format:
If the length of send data (from STX to BCC) exceeds 136 bytes, it is divided into blocks by ETB.
In this case, the succeeding divided data is sent after STX.
1. STX
STX is the transmission control character which indicates the start of the text transmission (identifier
and data).
2. Identifier (2 digits)
The identifier indicates the type of data (measured value, status and set value) sent to the host
computer.
Refer to 8. COMMUNICATION DATA LIST (P. 8-1) .
3. Data
Data which is indicated by an identifier of this instrument, consisting of channel numbers, data, etc.
Each channel number and data are delimited by a space (20H). The data and the next channel number
are delimited by a comma (2CH).

Channel number: 2-digit ASCII code, not zero-suppressed. Channels without channel numbers
may exist depending on the type of identifier.

Data: ASCII code, zero-suppressed with spaces (20H). The number of digits varies
depending on the type of identifier.
Memory area soak time monitor and Area soak time become the following data:

When data range is 0 hour 00 minute to 99 hours 59 minutes:
Data range is 0:00 to 99:59, punctuation of time unit is expressed in colon “: (3AH).”

When data range is 0 minute 00 second to 199 minutes 59 seconds:
Data range is 0:00 to 199:59, punctuation of time unit is expressed in colon “: (3AH).”
