Introduction

1 Introduction

Thank you for buying a KS 50-1 TCont.
This expert line unit offers special functions for tempering and hot-runner
equipment. An optional 20mA current loop or an RS485/422 interface are
available for easy connection of peripheral units including a KS 50-1 TCont to a
machine control system.
The protocol is widely used in the plastics industry and supported by many
injection moulder and extruder manufacturers, e.g. Arburg, Engel and
Krauss-Maffei. Another name for it is ”ARBURG protocol”.

This operating note describes the extended functions and features of
KS 50-1 TCont. For all other functions, refer to operating manual
9499-040-62811 for KS 50-1 Industrial Controller.

1.1 Definitions

A current loop interface transmits serial data by switching on and off a 20mA
current in a conductor loop at the data bit clock. During the rest condition, or
during transmission of ”1” bits, a constant 20 mA current is flowing, whilst the
current flow is intermittent with ”0” bits.

Another name for 20mA current loop interface is TTY interface
(TeleTYpe(writer)).

l

Caution! The unit contains ESD-hazarded components.

3.2 Behaviour after power-on

After supply voltage switch-on, the unit starts with the remote mode and goes
then into the standby mode. The controller mode is switched off. (SP = OFF).

3.3 Functions for tempering units

KS 50-1 TCont has a lot of possibilities to connect signals coming from and
going to the tempering unit.

The process value is connected to INP1.

w

An output signal of a safety temperature limiter (STL) can be attached

w

alternatively to di1 to di3. When responding the STL the controller goes into
the switching off mode (stop). The signal is passed on in the protocol (see
page 18).

Operation

The operation of the controller can be accomplished in the remote or in local

w

operation. For the change-over the inputs di1 to di3 or the F-key are
available. In remote mode values can be given only over the attached
interface; inputs via the front are blocked. Vice versa in local mode set-point
operations over the interface are not permitted. As answer the device
supplies a NAK message.

For local starting and stopping of the tempering unit push-buttons or

w

switches can be selected and attached at the inputs di1 to di3. The function
start or stop is released with the change of 0 to 1, independently of the
configuration of di.Fn as push-button or switch.

Selected signals for sensor mode, level alarm or flow alarm can be connected

w

to di1 to di3. They are only through-handed in the device, but indicated in
the protocol (see page 17).

The alarm for safety temperature - monitoring can be determined with limit 1

w

( Lim.1).

KS 50-1 TCont supplies a continuous signal to control a pump, which can be

w

connected to OUT1 to OUT6.
After a stop command the pump is only switched off, if the return flow

w

temperature is fallen below the adjusted limit, which is defined over the
set-point SP2.

g

If the inputs for start and stop are not wired, then the same functionality can be
achieved in local mode by switching on and off the controller function (for
switching off put the set-point SP to OFF; for switching on enter a valid
set-point). The start instruction corresponds to the control command (r) in the
remote mode, the stop command to the control command (p).

Operation

3.4 Functions for hot-runner

To operate with the protocol extension for hot-runners only a few additional
inputs and outputs are needed.

In local operation a start-/stop functionality can be achieved by switching on and
off the controller (for switching off put the set-point SP to OFF; for switching
on enter a valid set-point). The start command corresponds to the control
command (r) in the remote mode, the stop command to the control command (a).

The operation of the automatic controller can be switched over from remote

w

to local operation. Therefore the inputs di1 to di3 or the F-key are available.

Hints on self-tuning

To meet the special requirements of fast control loops, e.g. with tempering units,
the following information should be taken into account.

By setting the input filter for measurement input 1 ( Para / InP.1 / t.F1)toa
filter time
the input variable.

To improve the optimization result, the control range should be limited to the
actual range. For this purpose, the min. and max. control range limit must be

matched, e.g. with a range of 20°C ... 150°C, value rnG.L = 20and rnG.H =
150 in Conf / Cntrmust be set.

The minimum cycle times t1 and t2 should be as low as possible. If a defined
min. pulse duration must not be exceeded, changing during self-tuning can be
prevented via configuration parameter Adt0 = 1. Please, note that the shortest
pulses result from ¼ x t1 or¼xt2.

≥ 15 s, input variable fluctuations can be reduced, i.e. earlier settling of

Communication protocol

6 Communication protocol

KS50-1 TCont supports a simple protocol for injection moulders and extruders
widely used in the plastics industry, which is used for connecting peripheral
equipment and easy simple data exchange. This protocol, which is also called
”ARBURG” protocol, is designed according to the specification of the Arburg
company.

g

This protocol is also supported by other machine manufacturers, e.g. Engel,
Krauss-Maffei, etc. Any adaptation required can be done by changing the
Baudrate or the parity.

Communication is according to the master / slave principle. KS 50-1 is always
slave and polled for a message by the machine control system. Exchanging
messages is done in half-duplex operation.
The transmission parameters are adjustable via the front panel or via

Communication protocol

6.1 Data format

For transmission of block length and checksum, the hexadecimal format is used,
whilst set-points and process values are transmitted in BCD format. For
transmission, hexadecimal values are converted into ASCII. For simplification,
values above 9 (A-F) are coded as 3Ah - 3Fh instead of 41h-46h (ASCII A-F).

Byte 2-4: Block length; each message contains 3 bytes, which include

(ASCII-coded) the binary number of bytes of the overall message

8 Protocol for hot-runner systems

Selecting the hot-runner protocol is done via setting ProT =2.
With a hot-runner system, KS 50-1 TCont covers one channel.

8.1 Master telegram

The structure of the inquiry telegram is:

...4 5 6 ... 10 11+12
... Identification Message Checksum

Byte 5: Identification: 41h (‚A‘) is supported.

Byte 6-9:

• Set-point with command for closed-loop control: (= SP)in0,1 °C

(3 digits before, 1 digit behind the decimal point);
Negative temperatures up to –99 °C are possible (1

• Output value with command for positioning: in % (= Yman)

(3 digits before, 1 digit behind the decimal point)

Byte 10: Control commands

72h (r): closed-loop control (normal operation),

in °C; instrument in automatic mode;
after control function switch-off, self-tuning is done,
if permitted

73h (s): positioning,

in %; instrument in manual mode

61h (a): switch off channel

control function switched off

Byte 11-12: Checksum

st

byte = 2dh)

g

Special case: first message after control system start-up: system can read up to 25
channels per device address. Therefore, the message contains up to 25 times the
set-point or output value, and the control command.
However, a KS 50-1 TCont only uses the values for channel 1 from the message,
and indicates in the reply that only one channel is provided.

8.2 Slave telegram

The structure of the slave telegram is.

...4 5 6 ... 12 13+14
... Identification Message Checksum

Byte 5: Identification: 41h (‚A‘) is supported.

Byte 6: Status device

Bit 0 1: power supply failure during operation

(e.g. heating current alarm)
Bit 1, 2 (fixed) 0 0
Bit 3 1: other internal error, e.g. E.1, E.2 ...
Bit 4, 5, 6, 7: (fixed)0110

Byte 7-10: Channel 1

• Process value with command for closed-loop control: (= In.1)in0,1
degrees Celsius
(3 digits before, 1 digit behind the decimal point); negative
temperatures up to –99 degrees Celsius are possible (1st byte = 2Dh)

• Output variable
(3 digits before, 1 digit behind the decimal point)

with command for positioning: in % (= Ypid)

Byte 11: Channel 1 : status alarms 1

Bit 0 1: switched on ( C.Off =0)
Bit 1 1: lowering on (with SP.2 =1)
Bit 2 0: closed-loop control (automatic),

1: positioning (manual mode)
Bit 3 (fixed) 0
Bit 4, 5, 6, 7 : (fixed)0110

Byte 12: Channel 1 : status alarms 2

Bit 0 1: lead break, e.g.: LooP =1
Bit 1 1: only undercurrent, e.g. HCA =1
Bit 2 1: sensor defective, e.g. FbF.1 , Sht.1 , POL.1
Bit 3 0
Bit 4, 5, 6, 7 : (fixed)0110

Byte 13-14: Checksum
