The Axioline P remote I/O system guarantees maximum availability for your application. With S2 redundancy, two PROFINET controllers can communicate with the I/O station at the same time. The hot-swap-capable local bus enables the replacement of existing modules from an Axioline P I/O station without the system having to be switched off. The electromechanical design of the bus socket means that you can actually remove several modules from the station simultaneously, even without disrupting local bus communication.

Axioline P – intrinsically safe I/Os

The intrinsically safe I/O modules can be installed in zone 2 and are suitable for the use of sensors as well as actuators up to zone 0. They feature HART communication and NAMUR functionality, making them particularly suitable for process automation applications.

Axioline P – combination of standard and intrinsically safe I/O modules

Standard modules can be combined with intrinsically safe modules particularly easily in the Axioline P I/O system. By positioning a partition plate (available as an accessory), the blue intrinsically safe modules can be added to the end of a station.

Axioline P – intrinsically safe I/Os without additional power supply

With the power supply integrated into each I/O module, the setup of an Axioline P station does not require an additional power supply. Furthermore, hot-swap capability is established when modules are removed due to the permanently live bus sockets.

Axioline P – topology

The modular station communicates with a PROFINET controller, for example a distributed control system (DCS), via a bus coupler. As an option, you can connect up to eight PROFIBUS PA segments to the individual proxy outlets in a compact way. To ensure the individual segments are immune to interference, appropriate shield connection technology is available. PROFIBUS PA sensors are connected directly to the modular Axioline P proxy.
Proven fieldbus technology, such as HART and Modbus/RTU, can therefore be integrated into PROFINET networks. This is done using PROFIBUS PA gateways that are connected to the modular Axioline P proxy.

Space

Up to three different I/O stations can be built from the Axioline P portfolio. With the AXL P BK PN AF bus coupler, you can set up either a pure PROFINET or PROFIBUS PA proxy using the fieldbus power supply modules. Or you can configure a hybrid remote I/O station by also adding the Axioline P I/O modules. Use the AXL P BK PN bus coupler in combination with corresponding I/O modules to realize a homogeneous I/O station.

Connection through to zone 0

Axioline P devices can be connected directly to a distributed control system (DCS) in the form of a remote I/O system. PROFINET S2 system redundancy is supported, which ensures very reliable communication between the I/O station and DCS.
The Axioline P system can be installed in zone 2, and allows a direct connection of sensor and actuator signals from zones 2, 1, and 0. The portfolio includes important functions for process automation, such as analog input and output modules for HART communication as well as digital input modules for connecting NAMUR sensors.
This allows you to integrate intrinsically safe modules into the I/O station without additional components.
