Application

SIMATIC ET 200AL is a distributed I/O device with degree of protection IP65/67 and easy handling and installation.
Due to the high degree of protection and robustness, small dimensions and low weight, ET 200AL is especially suitable for use at the machine and on moving plant sections.

SIMATIC ET 200 permits the user to access digital and analog signals and IO-Link data via PROFIBUS or PROFINET at low cost.

Design

  • Variable and modular station configuration:
    Using a bus cable, the I/O modules are interconnected, or connected to the interface module or the ET 200SP I/O system via an internal backplane bus (ET connection). The modules can be installed up to 15 m apart from each other.
  • Compact dimensions for use in extremely confined spaces:
    the width of the interface module is 45 mm; the I/O modules are 30 mm or 45 mm wide.
  • Can be mounted directly in a machine or assembly line:
    screw fastening through the front or side in all mounting positions, both on even surfaces or on aluminum mounting rails using sliding blocks.
  • Maximum configuration:
    • PROFINET: max. 32 I/O modules with 1430 bytes of input/output data each.
    • PROFIBUS DP: max. 32 I/O modules with 244 bytes of input/output data each.
    • ET 200SP: max. 16 I/O modules.
  • Module wiring:
    The module is connected via the internal backplane bus (ET connection) by means of a bus cable and power is supplied via power supply cables, in both cases with the M8 connection system. Different types of pre-assembled cables in various lengths are available for this purpose. The identical coloring of the system interfaces and system cables and the meaningful interface designations permit quick and easy assignment during wiring.
  • Signal wiring:
    • I/O modules with M8 or M12 connection technology for the connection of digital signals.
    • I/O module with M12 connection technology for the connection of analog signals.
    • IO-Link Master with M12 connection (port type B) for the connection of IO-Link devices.
  • Integrated cable tie:
    due to the integrated cable tie opening in the modules, the cables can be bundled and supported direct at the module if required.
  • Labels:
    For the identification of channels, modules and slots; supplied with the modules. The labels can be mechanically inscribed using commercially available labeling systems.

Interface modules

The following interface modules are available:

  • IM1 57-1 PN, for connecting ET 200AL to PROFINET
  • IM1 57-1 DP, for connecting ET 200AL to PROFIBUS DP

The interface modules have two backplane outlets (ET connection 1 and 2) to which the I/O modules are connected.
The I/O modules are connected to the ET 200SP I/O system via a ET 200SP bus adapter.

Function

Mode of operation

Via PROFINET, PROFIBUS or ET 200SP, a central controller can access the distributed I/O modules of the ET 200AL in the same way as central I/O modules.
Communication is carried out fully automatically between the I/O controller in the central controller and the IM 157-1 or IM 155. Interference-free internal data transfer using shielded cables.

Comprehensive, module-specific diagnostics with plain text messages enables rapid location and elimination of system faults in the shortest possible time. Annoying plant downtimes belong to the past, and availability is significantly increased.

Configuration, parameterization and diagnostics

The ET 200AL is configured and assigned parameters via TIA Portal, STEP 7 or the configuration tool of the controller used.

The IO-Link master is configured using the S7-PCT (Port Configuration Tool).
