3.2.45 DWE_ - Digital Write Ethernet (V3.0)
DWE_ function blocks are available when the
optional Ethernet communication board
11
is installed
in the controller. It enables the controller to write
Digital data to other stations over the Ethernet
network.
Up to 32 DWE_ blocks are available. Blocks are
assigned in sequence, controller wide, with each use.
Digital data is On/Off data packed into a 16-bit word.
The IP ADRES parameter is used to configure the IP
address of the destination Modbus device. The MB
ADRES parameter allows a Modbus address to be
configured. When connecting to other Siemens
MOORE controllers the Modbus address is set to 1.
In some cases, other Modbus devices may use a
different address or when going through a Modbus
TCP/IP gateway a Modbus network may have
multiple devices, each having a unique address. The
MB REG parameter identifies the location of the
register in the Modbus device.
There are three write update options that can be
configured by the UD TYPE parameter.
1. oncE will write once to the START CL (Modbus
Starting Coil. The controller will write when any
block input value changes state.
2. P2P will update at the controller peer to peer rate set in the ETHERNET block.
3. Ct will update at the cycle time of the controller.
The Ct option is normally only used when writing time critical changes. Input T can be used to trigger a write. This
would be used in cases where the oncE option has been selected, input values do not change, and there may be a
concern that the receiving device has lost the values.
Output QS indicates the quality of the write operation and will go high (1) when the write is not completed
successfully. This is normally associated with failure of the destination device to receive data due to a
communication failure or a misconfiguration of the device.
