S5-100U Function Modules
Function
The S5-100U programmable controller offers different solutions for individual closed-loop control
tasks. First there is a software solution for CPU 103, version 8MA02 and higher, via function blocks.
Second, there is a control module solution (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 closed-loop control module IP 262 can be used with 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)
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 rpm controls.
Modules
There are two IP 262 modules.
• ... - 8MA12 with 3 analog outputs for continuous controllers with analog output signals
• ... - 8MB12 with 8 binary outputs for continuous controllers with pulse time-interval signals or for
step-action controllers
Additionally, the module provides the following inputs:
• 4 analog inputs for direct feed of setpoint and actual values
• 4 binary inputs for control variables
Installation
• The closed-loop control module is plugged into a bus unit like any other input or output module
(see chapter 3).
• The module can only be plugged into slots 0 to 7.
• The connections for power supply and the analog and binary output signals are located on the
terminal block of the bus unit.
• The analog and binary inputs are connected to the module with a 25-pin sub-D female
connector.
