Yokogawa DX Serial Driver
Control Command and Response
The Command address allows the user to send a string command and receive a string response to and from
the device. This allows the user to send any command to the device, including commands not directly
supported by the driver. This tag is only available to users logged in at the Administrator level; otherwise,
write operations will return an error.
Caution: Write operations using the Command address should be performed with extreme care.
Notes:
1. The actual number of addresses available for of each type depends on the configuration of the
Yokogawa device. If the driver finds at Runtime that an address is not present in the device, it will post
an error message and remove the tag from its scan list.
2. Addresses that have Write Only access are assigned a default access of Read/Write. However, data
values are unreadable for these addresses and the associated tags are not included in the scan list.
The current data value for these tags will always be 0 for numeric data types and null string for string
data types.
