FS-8700-30 – YorkTalk

FieldServer Driver – Serial
FS-8700-30
YorkTalk

Driver Code: SPEC
Version: 1.00

 

Device Options:

  1. York Translator – The recommended option: A direct RS232 connection is made to the chiller. This is a very cost effective option as a single FieldServer can support 8 simultaneous connections. The aggregate bandwidth is then also 8 times higher than in the case of a single multidrop connection to 8 devices.
  2. XL Translator – A RS232 connection is made to the XL Translator (also known as ISN LDC 17 – Link Data Controller), which in turn communicates with York devices via RS485. For this configuration, the York Chillers must be fitted with the “Linc Chiller” module to allow compatibility with the LDC’s RS485 network.
  3. MicroGateway – A RS232 connection is made to the MicroGateway, which in turn communicates with York devices via RS485. For this configuration, the York Chillers must be fitted with the “Linc Chiller” module to allow compatibility with the LDC’s RS485 network.

Notes (XL Translator, York Translator) :

The following combinations can be read:

  • 0-81 or any subset thereof
  • 82 by itself
  • 83-84 or any subset thereof
  • 85 by itself
  • 86 by itself

The following combinations can be written to:

  • 82 by itself. Only the value 0.0 (OFF) and 1.0 (ON)
  • 83 by itself
  • 84 by itself
  • 85 by itself. Will reset latched error code to 0.0
  • 86 by itself. Will reset latched error code to 0.0

The system is offset sensitive allowing single data blocks but multiple scan blocks.

The MicroGateway mode allows the f, s and p parameters (feature, section and page) to be specified directly for write messages, allowing all single-value fields (such as set points and digital outputs) to be written. For read messages, only f54 is available, but the section (s parameter) can be specified as required to address different devices.
