When CIO 000000 and A20206 (the Communications Port Enabled Flag for
port 06) are ON, EXPLT(720) reads the Total ON Time (s) or Number of Con-
tact Operations from a DRT2 Slave (I/O Terminal). In this case, the Total ON
Time or Number of Contact Operations for input 3 are read.
Service Code = 0E hex, Class ID = 09 hex, Instance ID = 03 hex, and Attribute
ID = 66 hex.
For example, a value of 2,752,039 s is returned as the response for the Total
ON Time.

Number of bytes of data: S+1 to S+5 = 5 words = 10 bytes = 0A hex
Slave's node address = 45 = 2D hex
Service Code = 0E hex
Class ID = 09 hex
Instance ID = 03 hex (Input 3)
Attribute ID = 66 hex
Contains 08 hex for 8 bytes of received data in response frame.
Returns Slave's node address = 45 = 2D hex.
Service Code = 8E hex (normal completion)
Service Data = 0029FE27 hex (2,752,039 s decimal)
Set 5 words = 0005 hex since there are 5 words in D to D+5.
Byte order = 0 hex (from leftmost byte), communications port = 6 hex
(port 6), and the DeviceNet Unit's unit address = 12 hex
Response monitoring time = 0000 hex (2 s)
