FieldServer Driver
FS8700-106
Rapid Engineering ICSI or ICSII Controller Protocol
Description
This driver is used to exchange data between a FieldServer and an ICSI or ICSII HVAC controller device manufactured by Rapid Engineering.
The driver is a serial driver using a RS485 serial port to connect between the FieldServer and the ICSII capable device.
The driver provides client functionality.
As a client the driver can poll for data from the ICSI or ICSII device as well as being able to some control points and set points. Details are provided below.
Server functionality is built into the driver but is not documented or supported. This functionality is implemented to support our ongoing QC efforts.
| Fieldserver Mode | Nodes | Comments |
| Client | 99 | Up to 99 ICSI or ICSII devices can be linked on one RS485 network. The functional specification of the EIA485 standard limits the number of nodes per segment to 32. If additional network segments are required then repeaters are required. The network must consist exclusively of ICSI or ICSII devices. For mixed configurations call for more info. |

Data Points
The FieldServer reads data from the ICSII device. The data points below are the points available to the FieldServer but this does not necessarily mean that they are valid for the HVAC device connected to the ICSII.
