Class Description
Device server for Wago 750 series Programable Fieldbus Controllers and Fieldbus Couplers. The class supports reading and writing to a node consisting of a number of Wago modules. It communicates with device over Modbus TCP or RTU protocol by means of Modbus Tango class.

Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State Device state |
This command gets the device state (stored in its device_state data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Device status |
This command gets the device status (stored in its device_status data member) and returns it to the caller. |
| DevReadNoCachePhysInput: DevShort Logical device index. Output: DevVarFloatArray Array of values. |
Read all physical values of the specified logical device and // return the values as a float array. Physical value are // calculated from module registers according to a predefined // algorithm deduced from the module type in the catalogue. // Read registers from the cache. // // Note: not all the channels of the logical device are // returned but only the ones on modules marked as specials // in the catalogue. |
| DevWritePhysInput: DevVarFloatArray Logical device key and values for write Output: DevVoid |
— |
| DevReadPhysInput: DevShort Logical device key Output: DevVarFloatArray Placeholder for obtained values |
Read physical values of LD |
| DevWriteDigiInput: DevVarShortArray Logical device key, then pairs of channel,value. Output: DevVoid |
Write words and bits to output module registers. |
| DevReadDigiInput: DevShort Logical device Output: DevVarShortArray Array of bit values |
Read all input and output word and bits of the specified logical device and return the values as a short array (short per bit). Read from the cache. |
| DevReadNoCacheDigiInput: DevShort Logical device Output: DevVarShortArray Array of bit values |
Read all input and output word and bits of the specified logical device and return the values as a short array (short per bit). Read from the cache. |
| DevGetKeysInput: DevVoid Output: DevVarShortArray Numerical keys |
Return all the numerical keys known by the server. |
| DevKey2NameInput: DevShort Numerical key Output: DevString Logical device name |
Return the logical device name associated to a numerical keys name. |
| DevLog2HardInput: DevVarShortArray [0] : logical device key [1] : logical channel Output: DevVarShortArray [0] : offset in wago controller memory (ex: 0x16) [1] : MSB=I/O LSB=Bit/Word (ex: 0x4957 = (`I`<<8)+`W`) [2] : module reference (ex: 469) [3] : module number (1st is 0) [4] : physical channel of the module (ex: 1 for the 2nd) |
Return hardware information of a logical device/logical channel. |
| DevHard2LogInput: DevVarShortArray [0] : MSB=I/O LSB=Bit/Word (ex: 0x4957 = (`I`<<8)+`W`) [1] : offset in wago controller memory (ex: 0x16) Output: DevVarShortArray [0] : logical device key [1] : logical channel |
Returns the logical device/logical channel of a memory location on wago controller |
| DevName2KeyInput: DevString Logical device name Output: DevShort Numerical key |
Return the logical device name associated to a numerical keys name. |
| DevWcCommInput: DevVarShortArray [0] : code of command to execute (ex: 0x010c for ILCK_RESET) [1] : 1st parameter [2] : 2nd parameter etc Output: DevVarShortArray [0] : 1st argout or error code [1] : 2nd argout etc |
Executes a command in the wago controller programm. The communication is done using the ISG protocol. |

| Name | Description |
|---|---|
| modbusDevNameDevString | Name of Modbus tango device server used for communication with physical device. |
| configArray of DevString | Configuration of physical modules in device and its projection to LogicalDevices in server. |
| updatePeriodDevUShort | Modbus process image cache update interval. |
| modulesCatalogueArray of DevString | List of know WAGO modules usable by the WAGO Device Server SYNTAX: -the first item should be the date the list has been updated -then, for each module, you must supply: -module reference -number of digital inputs -number of digital outputs -number of word inputs -number of word outputs -number of logical channels (typically SSI32bits==2 words) -string for special module (``none``,``ssi``,``thc``,``thck``,etc) -string for description |
