Function
SIMATIC S5-90U and SIMATIC S5-95U offer different solutions for individual closed-loop control
(PID) tasks. First there is a software solution via function blocks (only for the S5-95U) and second,
a control module (for example, a module that can solve PID control tasks simply and in a time saving
manner). The basis, in both cases, is a PID-control algorithm.
The IP 262 closed-loop control module can be used with any of the S5-90U, S5-95U, and S5-100U
programmable controllers. It can be used without COM software.
The module relieves the programmable controller from closed-loop control tasks. The IP 262 also
works with its own power supply in a stand-alone operation. The module can function independently
without a programmable controller and can handle up to four closed-loop control circuits.
Two interfaces are located on the front panel of the module.
• An interface for the connection of a programmer (PG) or an operator panel (OP) or the
SINEC L1 Network (under development)
• An interface for the connection of analog and binary inputs
In addition, the following items are available.
• A selector switch for each channel for current and voltage (thermocouples or PT 100)
• A status LED for RUN (a continuously lit green light), transducer malfunction (blinking light), and
module malfunction (off)
Additionally, the module offers the following inputs.
• 4 analog inputs for direct feed of setpoint and actual values
• 4 binary inputs for control variables
The module is well-suited to take over control-loop tasks in the area of industrial processing
technology, for example, temperature control, pressure and flow control, continuous injection
functions, and non-time-critical closed-loop speed controls.
Modules
There are two IP 262 modules.
• ... - 8MA 12 with 3 analog outputs for continuous controllers with analog output signals
• ... - 8MB12 with 8 binary outputs for continuous controllers with pulse time interval signals for
step-action controllers
