6-2 Sending CompoWay/F Commands to a Temperature
Controller
Using a CS/CJ-series DeviceNet Unit
Set and send the timer as follows:
1. From the Configurator, select Network and Connection to switch to online
operation.
2. Select and double-click the CS/CJ-series DeviceNet Unit.
3. Set the value of the message timer for the applicable DeviceNet Commu-
nications Unit node address to 6000 ms. (In the following display, the De-
viceNet Communications Unit node address is 0.)
4. When sending explicit messages using the CMND instruction, set the re-
sponse monitoring time to 6000 ms or longer.
Using C200HX/HG/HE, or CVM1/CV-series DeviceNet Master Units
When sending the explicit message IOWR instruction, set the response moni-
toring time to 6,000 ms. (The message timer cannot be set from the Configu-
rator.)
The master can send CompoWay/F command frames to the DeviceNet Com-
munications Unit by embedding them in explicit message commands, and
receive CompoWay/F response frames that are embedded in explicit mes-
sages responses.
When the DeviceNet Communications Unit receives the explicit message
command, a CompoWay/F command frame is created by adding STX, ETX,
and BCC to the command frame data, from the unit number to the FINS-mini
command text, after which it is sent to the Temperature Controller. The Tem-
perature Controller returns a CompoWay/F response.
When the DeviceNet Communications Unit receives the CompoWay/F
response returned from the Temperature Controller, the STX, ETX, and BCC
values are deleted, and then the data is converted to an explicit message
response in either hexadecimal or ASCII format, before it is sent to the mas-
ter. (The DeviceNet Communications Unit performs a BCC check.)
