GE Fanuc SRTP Ethernet Driver
The GE Fanuc SRTP Ethernet driver can be used to connect the HMI device to the GE controllers
using the native and proprietary SRTP communication protocol.
Protocol Editor Settings
Add (+) a driver in the Protocol editor and select the protocol called “GE Fanuc SRTP” from the list of
available protocols.

Tag Import
The GE Fanuc SRTP Ethernet driver support the Tag Import facility. The symbol file can be exported
by the controller programming software (Proficy Machine Edition from GE Intelligent Platforms).
In the Proficy Software, click on the “Variables” tab and then from the right mouse click select the
Export option from the contextual menu as shown from the following figure.

Locate the “.CSV” file and confirm.
The tags present in the exported document are listed in the tag dictionary from where they can be
directly added to the project using the add tags button as shown in the following figure

Data Types
The import module supports variables of standard data types as per the following list.
BOOL
BYTE (8-bits unsigned integers)
DINT (32-bits signed integers)
DWORD (32-bit bit strings, displayed as unsigned integers)
INT (16-bit signed integers)
REAL (32-bit floating point data)
STRING (character string)
UINT (16-bit unsigned integers)
WORD (16-bit bit strings, displayed as unsigned integers)
Note: User defined structure and predefined structures are not supported. 64-bit data are also not
supported.

Aliasing Tag Names in Network Configurations
Tag names must be unique at project level; it often happens that the same tag names are to be used
for different controller nodes (for example when the HMI is connected to two devices that are running
the same application). Since tags include also the identification of the node and Tag Editor does not
support duplicate tag names, the import facility in Tag Editor has an aliasing feature that can
automatically add a prefix to imported tags. With this feature tag names can be done unique at project
level.
The feature works when importing tags for a specific protocol. Each tag name will be prefixed with the
string specified by the “Alias”. As shown in the figure below, the connection to a certain controller is
assigned the name “Node1”. When tags are imported for this node, all tag names will have the prefix
“Node1” making each of them unique at the network/project level.
Figure 7
Note:
Aliasing tag names is only available when tags can be imported. Tags which are added manually in
the Tag Editor do not need to have the Alias prefix in the tag name.
The Alias string is attached to the tag name only at the moment the tags are imported using Tag
Editor. If you modify the Alias string after the tag import has been completed, there will be no effect on
the names already present in the dictionary. When the Alias string is changed and tags are imported
again, all tags will be imported again with the new prefix string.

Communication Status
Tech-note
The communication status can be displayed using the dedicated system variables. Please refer to the
User Manual for further information about available system variables and their use.
The status codes supported for this communication driver are:
Error
NAK
Timeout
Invalid response
General Error
Notes
Controller replies with a not acknowledge.
Request is not replied within the specified timeout period; ensure the
controller is connected and properly configured for network access
The panel did receive from the controller a response, but its format or its
contents or its length is not as expected; ensure the data programmed in
the project are consistent with the controller resources.
Error cannot be identified; should never be reported; contact technical
support
