Omron DRT2 SERIES DEVICENET SLAVES - OPERATION MANUAL 04-2008 Operation Manual page 562

Restrictions on Reading Total ON Time/Contact Operation Counter for All Slaves at Once
Ladder Program System Configuration
PLC: Master
Node: Number 30
Slave: Node number 00
Note The ladder program reads data for one Slave at a time.
Operation Specifications
The following table shows the applicable models (with manufacturer revision 1.01).
Slave name
Remote I/O Terminal with 16 inputs
Remote I/O Terminal with 16 outputs
Environment-resistive Terminal with 8 inputs
Environment-resistive Terminal with 16 inputs
Environment-resistive Terminal with 8 outputs
Sensor Connector Terminal with 16 inputs
Note 1. The (-1) suffix refers to models with PNP.
2. The read command cannot be used with DRT2-ID16(-1) and DRT2-OD16(-1), even if an Expansion
Unit is mounted to the Remote I/O Terminal.
3. DRT2 Slaves not mentioned in the above table support the Monitor Status for Total ON Time or Con-
tact Operation Monitor for All Slaves Read at Once command, even if the Slaves are models with
manufacturer revision 1.01. Therefore, the ladder program shown here is not required.
Ladder Program Specifications
• When the start bit 0.00 turns ON, data starts being read for each individual terminal automatically, and the
response is then transferred altogether as batch read data to DM 00050 to DM 00055.
• When one portion of the processing is completed, the end bit 0.02 turns ON.
• If the command needs to be executed again, after the end bit 0.02 turns ON, turn OFF 0.00 again, and
then execute the program.
Note 1. The model is automatically recognized by the ladder program, so the ladder program does not need
to be changed to suit each model.
2. In the following programming examples, the Master is node number 30 and the Slave is node number
00.
3. To change the node numbers, edit the program as follows:
Changing the Master's Node Number
Change the upper byte of the constant part of the MOV21 #1FFE DM 00003 command in the ladder program.
Example: Change to #3FFE for a Master with node number 63.
Changing the Slave's Node Number
Change the upper byte of the constant part of the MOV21 #000E DM 00011 command in the ladder program.
Example: Change to #0F0E for a Slave with node number 15.
Response Area
Use words DM 00050 to DM 00055 to store the data. The internal processing areas are also reserved, so refer
to the list of used areas.
