CompoWay/F Message Communications
Section 4-5
Response Block
The following diagram shows the command text in the CompoWay/F response
block.
Number of Elements
Specifies as hexadecimal ASCII the number of Units starting from the speci-
fied unit number that are to be read from. The leftmost bit is set to 1. There-
fore, the number of elements is set to “8001” to read one Unit. Unless
executing Read Threshold Setting, the number of elements can be set to
“8001” only.
Read Data
Gives the data read in hexadecimal ASCII.
The following information describes the data format for each item.
Read Number of Sensors
Connected
Reads as a 4-digit hexadecimal value the number of Sensors connected.
When DIP switch pin 3 is ON, the value is read from the internal memory, and
when pin 3 is OFF, it is read from the rotary switch setting. The data range is
0001 Hex to 0010 Hex (1 to 16 Units).
Read Response Delay
Time
Reads as a 4-digit hexadecimal value the Communication Unit’s response
delay time (time for a CompoWay/F response to be returned). The unit is ms.
Some CompoWay/F masters, such as CQM1H Serial Communications
Boards, cannot read responses that are returned too quickly. For such mas-
ters, the Communication Unit response delay time can be set by using the
Write Response Delay Time command. The default setting is 0 ms.
Read Threshold Setting
Reads as a batch the threshold settings for the number of Sensors specified
in the number of elements after the unit number specified in read start
address. The data is given as a 2-byte (4-digit) hexadecimal value for each
Unit, and negative data is expressed as its two’s complement.
Unit number specified in the read start address: Unit number N
Number of Units specified in the number of elements: M Units
