MotionPLC GEL 8240
General information
The controllers have an integrated PLC, field bus systems
and multi-axis control with a maximum of 11 controlled axes
(max 3 with ± 10 V and max. 8 with CAN bus). 64 axes altogether
can be controlled via the CAN bus (without feedback).
Additional inputs and outputs permit several CAN
REMOTE I/Os with up to 64 inputs or outputs per node and
up to 64 node addresses.
The standard CoDeSys programming environment runs in
parallel with the multi-axis control and offers full transparency
for all parameters. Parametrization of all 7 axes is effected
by a PC tool and offers menu-guidance for comfortable setting
of the usual parameters.
The standard programming environment in acc. with IEC
61131-3 includes a library of ready-made and powerful technology
functions for terminal programming and automatic
motion control.
Up to four different communication channels are available
with one interface enabling all conventional field bus systems
(PROFIBUS-DP, DeviceNet,...) to be used.
The field bus modules can be retrofitted or replaced at any
time without the need to modify the PLC program.

Overview
Connection assignment
PLC programming environment
IEC 1131-3 is an international standard for programming languages adapted to stored-program control units. The programming languages realized in CoDeSys are in conformity with the requirements of the standard. They can be mixed whenever needed and are partially convertible.
Instruction list (IL)
An instruction list (German: Anweisungsliste AWL) is composed of a sequence of instructions. Each instruction begins in a new line and consists of an operator and - depending on the type of operation - of one or several operands separated by
Ladder diagram (LD)
The ladder diagram (German: Kontaktplan KOP), too, is a graphics-oriented programming language which is basically similar to an electrical circuit. It consists of a series of networks. A network is limited on the right and left side of the plan by a vertical current path. In between, there is a circuit comprising contacts, inductances and connecting lines.
Function block diagram (FBD)
The function block diagram (German Funktionsplan FUP) is another graphics-oriented programming language. It is organized by lines and uses a list of networks, each containing a structure representing respectively a logical or an arithmetical expression, the recall of a function block, a jump or a return instruction.
Structured text (ST)
The structured text is a series of instructions which can be executed - as in the higher programming languages - depending on a condition ( „IF..THEN..ELSE “) or iteratively (WHILE..DO).
Sequential function chart (SFC)
The sequential function chart (German: Ablaufsprache AS) is a graphics-oriented language to describe the sequential execution of different actions in a program.
Continuous Function Chart Editor (CFC)
The essential difference with regard to the FBD is the free arrangement of function blocks. CFC is a useful enlargement of the IEC 1131-3 standard.
Operating software

lengthening, shortening, etc.
Within the scope of supply
BB2100K operating software
The BB2100K operating software can be used to define the desired curve characteristics on a PC. The PC is connected to the MotionCard via the serial interface. The parameter editor for the servo-converter LD 2000 can also be started out of this program. Other program characteristics:
System parameter editor Oscilloscope function Setting of range signals via mouse-click
Curve editor example
Individual programming due to free editing of program texts Assistance with the analysis of curves (position, speed, acceleration and torque) Graphics-aided editing of parameters for special applications (e.g. rotating cutter and flying saw)

Application of adhesive on a car door
An glue dispenser with a three-axis portal equipped with servo drives and amplifiers is controlled by the MotionPLC in such a way that the tool follows a trajectory in three dimensions which has been fixed beforehand by a small number of essential tool center points in the teach-in mode.
