PhoenixContact I/O Modules
PhoenixContact provide stackable Input/Output modules for the Axioline F-series bus couplers. These I/O modules are interchangeable between bus couplers in the AXL-F-series product range, such as AXC 3050 and AXC 1050. For more information about the details of each specific PhoenixContact I/O module, please consult the Phoenix Contact website, and do a search for the specific module.
AXL F BK ETH
CDP Studio ModbusIO supports most of the Axioline analog and digital modules for the AXL F BK ETH. To see which specific modules are supported by CDP Studio, add a PhoenixContact-AXL-F-BK-ETH-UDP or a PhoenixContact-AXL-F-BK-ETH-TCP from the ModbusIO Resource tree. Select the IO packet and observe in the PhoenixContactIOModules resource to see which modules are supported.
The AXL F BK ETH bus coupler has a default IP Address of 0.0.0.0, so it must be set by either bootp or via the rotary switch on the bus coupler. The bus coupler reads analog and digital values from modbus address 0x1f40 (8000) and writes analog and digital values to modbus address 0x2328 (9000), in the order the modules are stacked physically.
Note: See the AXL F BK ETH Modbus TCP documentation on the PhoenixContact website for more information about which modbus addresses can be accessed, how to set IP Address and so on.
Configuration
The PhoenixContact-AXL-F-BK-ETH-UDP and PhoenixContact-AXL-F-BK-ETH-TCP are already set-up with a Modbus packet that has the correct read and write address for Modbus communication with the bus coupler, along with other settings required for correct Modbus communication. If required, additional Modbus packets can be added from the PhoenixContactIOModules resources. For instance, a watchdog initialization packet can be sent on Init (SendMode for the Packet is set to Init to only send it once on initialization).
Tools
The PhoenixContact AXL F BK ETH runs a web-interface on http port 80. It can be used to inspect the I/Os and to set watchdog timeout etc.
Notes
Note: Whenever modules are changed, added or removed, make sure to power-cycle the bus coupler, or the internal data-image might not be updated.
Note: Make sure to set the FunctionCode correctly, or there will be communication problems.
Note: In CDP Studio, I/O numbering start at 0, meaning that the first channel has the number 0.
