Siemens SIMATIC Interface Module Adapter

Innovation on Economical Base

Many plants operate with automation systems of previous generations. While performance might still be sufficient, obtaining spare parts and ensuring efficient service becomes increasingly difficult. To stay up-to-date, replacing the existing system with a modern unit is often necessary. However, this decision is frequently delayed due to the fear of disrupting production and the inconvenience of troubleshooting incorrect wiring.

Retrofit at Ease

The Interface Module Adapter (IMA) for SIMATIC S7-300 or SIMATIC S7-400 bridges the gap between old, field-proven production systems and the latest achievements in automation. The process involves taking off the front plug of the I/O units, replacing the automation system with an S7 controller, plugging in the IMA, and reattaching the front plug to the adapter. This is achieved through simple plug-in connections. After updating the STEP 7 software, production can resume.

Advantages are Obvious

• Low engineering costs in hardware; only the controller needs replacement. All wiring remains in place.
• Schematic diagrams do not require revision; signal lists are automatically updated by the software.
• Production shutdown time is reduced.

This procedure not only saves time and money but also reduces errors.

Structure S5 to S7-300

This section details the physical structure and technical data for connecting S5 systems to S7-300 systems using the adapter.

Technical data:

• Case with printed circuit board: H x B x T = 330 x 27 x 70 mm
• Connecting cable: l = 500mm
• Mounting bracket Set: H = 150 to 280 mm, B = 80 mm

S7-rail and S7-300 are not included.

Adapter Open Ended Type / Terminal Adapter

There are no adapters available for every possible combination. By using the adapter with an open cable end (cable length is 0.5m) or with terminals, you can create patches and wiring according to your own requirements.

This section describes the adapter for connecting S5-135/155U controllers to ET200SP modules.

The adapter consists of:

• Case with printed circuit board and S5-mating plug
• Connecting cable: l=600mm
• ET200SP BaseUnits

Technical data:

• Case with printed circuit board: H x B x T = 330 x 27 x 70 mm

The adapter consists of:

• Case with printed circuit board and S5-mating plug
• Connecting cable: l=500mm
• ET200SPHA BaseUnits

The adapter is mounted on the S7-300-rail; components of ET200SP HA use the rail of ET200SP HA. The mounting brackets (6EZ2041-8UG00-0BG0) are used for a two-level structure. Potential groups must be observed during planning. The ET200SP HA uses only 1 potential group, while the S7-135/155U is capable of more than one potential group. The supply can be set with a dipswitch.

• Case with printed circuit board: H x B x T = 330 x 27 x 70 mm
• Mounting bracket Set 6EZ2041-8UG00-0BG0

Profile rails, carrier modules and ET200SP HA-modules are not included.

Powersupply

Separation of potentials

There are floating or non-floating IOs. In both cases, the power for the module has to be supplied by the user. Another criterion is the short circuit protection of the signals. The outputs have to be tested for the rating of the pins and the printed conductor. Therefore, the power supply of signals is rooted in groups of 1/2/4/8/16.

Powersupply of inputs

Rooting

Conditions of Sale

The Interface Module Adapters 6EZ2 041-.. are intended for use between the front-plugs on the I/O modules of an obsolete controller and a modern replacement controller SIMATIC S7. Installation remains in place; only the controller and respective software need substitution. The best matching S7 components were selected for substitution, but deviations in specific performance may occur. Users must check limitations of their installation, including:

• Power supply
• Signal voltage
• Line-frequency
• Limits of I/O-definitions
• Rooting
• Number of channels
• Loading capacity
• Rating of connectors
• Signal switching frequency

If S7-units require external +/- potentials not supplied by the old installation, these must be brought to the terminal block on the adapter or to the S5 front connector. If power-rooting differs, additional jumpers may be needed. For installations fed from different power sources, an equipotential bonding contactor is required. The 'enable' signal of S5 units is not directly present in the S7 system. Parametering and mode selection for I/O units must align with S7 requirements. The vendor is not liable for damages from improper use. A field-test is recommended before general switch-over.
