The proportional coecient Kp is the controller amplification and determines how strongly the control deviation (the difference between the target temperature and
actual temperature) directly affects the control variable
(cooling down time). Kp values that are too large can
lead to the controller overshooting.
Integral time of PID (Ti 1):
The integral time Ti (s) is the correction time and determines how strongly the duration of the control deviation affects the control variable. Ti compensates an existing control deviation. A high Ti means a smaller and
slower effect on the control variable. Ti values that are
too small can lead to instability of the controller.
Differential time of PID (Td 1):
The differential time Td (s) is the derivative time and determines how strongly the rate of change of the control
deviation affects the control variable. Td compensates
for rapid control deviations. A high Td means a smaller
and slower effect on the control variable. Td values that
are too small can lead to instability of the controller.

start bit; 7 character bits; 1 parity bit (even); 1 stop bit.
- Transmission speed: 9600 bit/s.
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer’s request.
Command syntax and format:
The following applies to the command set:
- Commands are generally sent from the computer (Master)
to the device (Slave).
- The device sends only at the computer’s request. Even
fault indications cannot be sent spontaneously from the
device to the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive parameters are separated by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data) and
each response are terminated with CR LF (Code: hex 0x0d
hex 0x0A) and have a maximum length of 80 characters.
- The decimal separator in a number is a dot (Code: hex
0x2E).
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recommendations for the design of electrical plug connections for analogue and digital signal transmission on individual items of
laboratory control equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA co mmands serve only as low level commands for communication
between the device and the PC. With a suitable terminal or communications programme these commands can be transmit-
®
ted directly to the circulator equipment. The IKA software package, Labworldsoft
, provides a convenient tool for controlling circulating equipment and collecting data under MS Windows, and includes graphical entry features, for pump motor
speed ramps for example.
