Safetran-SCS-128 Description  
The Safetran-SCS-128 driver allows the transfer of data to and from devices over RS-232 SCS-  
128 protocol. Vital Harmon Logic Controller (VHLC) supports SCS-128 protocol. SCS-128  
80938-098 Rev A04 is the basis of the Safetran-SCS-128 driver. The FieldServer can act as a  
Client or a Server.  
Max Nodes Supported

Configuring the FieldServer as a Safetran-SCS-128 Client  
For a detailed discussion on FieldServer configuration, please refer to the FieldServer  
Configuration Manual. The information that follows describes how to expand upon the factory  
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files  
provided with the FieldServer).  
This section documents and describes the parameters necessary for configuring the FieldServer  
to communicate with a Safetran-SCS-128 Server.  
4.1.  
Data Arrays/Descriptors  
The configuration file tells the FieldServer about its interfaces, and the routing of data  
required. In order to enable the FieldServer for Safetran-SCS-128 communications, the  
driver independent FieldServer buffers need to be declared in the “Data Arrays” section, the  
destination device addresses need to be declared in the “Client Side Nodes” section, and  
the data required from the Servers needs to be mapped in the “Client Side Map Descriptors”  
section. Details on how to do this can be found below.  
Note that in the tables, * indicates an optional parameter, with the bold legal value being the  
default.

Configuring the FieldServer as a Safetran-SCS-128 Server  
For a detailed discussion on FieldServer configuration, please refer to the FieldServer  
Configuration Manual. The information that follows describes how to expand upon the factory  
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files  
provided with the FieldServer).  
This section documents and describes the parameters necessary for configuring the FieldServer  
to communicate with a Safetran-SCS-128 Client. When configured as a Server, the FieldServer  
is unable to keep synchronism with other Servers and Clients on the network if it is being polled  
using ‘Poll’ Function (i.e. single byte message). Therefore the FieldServer must be polled with  
‘Recall’ request for indication statuses. The FieldServer will always respond with the current  
statuses.  
The configuration file tells the FieldServer about its interfaces, and the routing of data required.  
In order to enable the FieldServer for Safetran-SCS-128 communications, the driver  
independent FieldServer buffers need to be declared in the “Data Arrays” section, the  
FieldServer virtual Node(s) needs to be declared in the “Server Side Nodes” section, and the  
data to be provided to the clients needs to be mapped in the “Server Side Map Descriptors”  
section. Details on how to do this can be found below.  
Note that in the tables, * indicates an optional parameter, with the bold legal value being the  
default.
