Scaling / Bit Packing

FieldServer's can scale data and manipulate values using some binary logic and arithmetic functions. Scaling can be applied to each block of Modbus Data read / served.

Move to change type : Convert from any FIeldServer Data Type to any other.

Move to pack/unpack bits and bytes: Its possible to address each bit in a 8,16 or 32 bit data element by using the packed data types.

Move to change byte/word order: Handle the endianess of the remote system easily.

Convert to/from Float, MK10, IEE754, 32 bit, 16 bit, 8 bit numbers

Move conditionally:

Perform Arithmetic Operation: + - * div sqrt, sqr ,

Perform Binary Logic Operation: And, Or, Not, >, >= , <, <=

Most functions can be configured to occur on a configurable period or on update of the data source.

Hot Standby

Its possible to configure selected FiedlServer models to act in Hot Standvy Mode. In one flavour of Hot Standby the two units are kept up to date all the time sharing the data from the field. In another mode, one unit is passive until it see's that the active unit is no longer responding.

Port Expansion

FieldServer can easily be configured to allows a Modbus RTU client to talk to a ModbusTCP server and vice versa. You do not need to tell the FIeldServer which registers to map from one to the other. You simply conifgure the FieldServer telling it which port and protocol to use for each node.
