Operating Modes

The following operating modes are possible in interface ope­ration:

■ Analog

■ Batch

Modules

Thanks to use of the modular design, every sera dosing pump connected to the INTERFACE MODULE can be parametrised ac­cording to their own requirements. It is possible to adapt the amount of process data precisely to the needed task.

Explanation of the modules

Input data The modules with the "CONTROL" ending are modules with process data sent to the pump. The pump can

be controlled and adjusted using these.

Output data The modules with the "STATE" ending are modules with process data received from the pump. These return

the status of the pump.

The modules can be used individually depending on the application and desired operating mode. However, the „PUMP_CON­TROL“ module must always be used for the control of the pump via the network as the operating mode is set here.
The pump can also be monitored for non-interface operating modes using the State modules.
All functions that can also be set using the hand-held control unit can be parametrised via the modules. Only timer operation
cannot be adjusted.
The Module Status LED lights continuously after the initialisation of the module by the pump.

The Operation Mode LED indicates the network status. It lights green continuously when process data are being exchanged with
a controller. It flashes green if the module is connected to a controller but no process data are being exchanged.

PROFIBUS acyclic data exchange

All modules can be addressed in Slot 1. The index number corresponds to the respective module number from the module table.
If data are read acyclically, the size of the data to be read must be specified using the length parameter of the DP-V1 request.
If more data are requested than the module provides, the INTERFACE MODULE only returns the data that are available in the
respective module. If fewer data than are available are requested, the module only returns data of the requested data quantity.

The module does not check the specified data length for acyclic requests.
If a greater data quantity than available is specified in PROFIBUS or PROFINET, the data cannot be accessed and the device
retains the last valid data.

OPERATION

Modules / Input

PUMP_CONTROL

This module is always necessary for the control of the pump irrespective of operating mode. The External Stop Bit that is valid
in all operating modes can be set with this module.
Other functions are the setting of the operating mode, reset of the totaliser, acknowledgement of alarms, stroke control for motor
pumps. If a valid interface operating mode is selected and the pump is not in interface operation, it automatically switches to
interface operation.

MANUAL_CONTROL

Adjustment of the stroke frequency / litre capacity in manual mode.
The operating mode in PUMP_CONTROL must be set to Manual Interface.

PULSE_CONTROL

A pulse for executing a stroke can be sent to the pump using the pulse bit. The pulse is detected during a flank change from
0 to 1. Furthermore, the functionalities of pulse parameters are shown. The stroke frequency / litre capacity can be set using
other input data.

ANALOG_CONTROL

Used for operation of the pump using analogue signal. The functionality of analogue parameters is shown via the input data.
A module for parametrisation of the analogue input is required for the operation.

BATCH_CONTROL

Start of a batch, reset of the remaining batch and changeover between „normal“ or „analogue“ batch possible.
Otherwise the batch quantity in strokes / litres and the stroke frequency / litre capacity can be set.

INPUT1_CONTROL, INPUT2_CONTROL, INPUT3_CONTROL

Setting of the inputs analogously to the menu.

OUTPUT1_CONTROL, OUTPUT2_CONTROL

Settings of the outputs analogously to the menu.

A_OUTPUT_CONTROL

Settings of the analogue output analogously to the menu.

MBE_CONTROL, SPEEDLIMIT_CONTROL, SLOWMODE_CONTROL, DOSING_CONTROL,
DEARIATION_CONTROL, LEVEL_CONTROL

Settings analogously to the Extras menu.

TIME_CONTROL

Setting of the system time of the pump.

CALIBRATION_CONTROL

The litre capacity of the pump can be calibrated with this module.

PUMP_INFO_STATE

General pump information, Dependent on the pump type.

ALARM_STATE

Display of the error signals of the pump. Active bit means error is present.

Settings (parameters)

The module is sent using the PROFIBUS address 126. Only the „SSA“ function is activated
with this address and a new address can be allocated via the network.
The address range 1-125 can also be set here if the addressing via SSA is not desired.
