TempLogger™ Version 6.5 released

TempLogger Machine Interface



The latest release of TempLogger can be integrated with machine control programs to replace timer based rotomoulding cycles with temperature based cycles. The Machine Monitor application is assumed to be, among other functions, the interface that the machine operators use. In the scenario that a Machine Monitor does not exist, then TempLogger could be used as the main machine application. TempLogger has two interface options:
  • RS232 serial COM port communications
  • TCP/IP communications

RS232 Communications

TempLogger communicates with the Base and Sender temperature recording units through a USB serial COM port. Data packets received by the Base unit from the Sender units are sent to a second RS232 serial port to provide communications with a PLC monitoring device that can interpret the temperature readings for machine control. TempLogger has an inbuilt serial COM port monitor that displays the communications data packages.

TCP/IP Communications

The interface uses the industry standard TCP/IP communication protocol to transmit data packages between computing devices on a network. The TempLogger application sends temperature readings and alarm activation events to the Machine Monitor application that communicates with the Machine PLC. TempLogger connects to the Machine Monitor automatically so that both applications can stream data between themselves.

Sample Program

A sample Machine Monitor program can be provided that demonstrates the way in which the interface operates. It is easy to develop or integrate into an existing application and uses a minimal amount of computer resources.

TempLogger™ Version 6.2 released

Machine PLC Interface


The interface uses the industry standard RS232 serial port communication protocol to transmit data packages between a TempLogger PC and a machine PLC device.
  • A Network RS232 serial port is used to communicate with the base and sender units and receive the temperature data packets.
  • A Machine RS232 serial port is used to communicate with the PLC device and send the temperature data packets.
  • The Network and Machine serial port numbers cannot be the same.
  • Up to 4 senders can be used to send temperature data to the PLC device.
Alarm Sounds
A sound file is used for each alarm relay number to alert operators when an alarm is triggered because the USB base unit does not have relays or a sounder.
  • A different sound file can be used for each relay.
  • Files sound1.wav to sound6.wav corresponds with relays 1 to 6.
  • An empty or invalid sound.wav file will make no sound.

Network Units

  • The base and sender units feature new wireless technology which includes: CE and RoHS compliance.
  • 2.4 GHz worldwide license free ISM Band frequency with signal strength indicator.
  • A USB powered base unit with no cables or external power.
  • Multiple log intervals for better temperature log results.
  • A smaller ULTRA sender unit specially designed for portability and testing.

Network Setup

The base and sender units connect automatically when powered on and transmit temperature readings every 5, 8 or 10 seconds, according to the log interval setting.

  • Each sender is identified by a unique ID.
  • Each sender is allocated to a base unit.
  • The sender assumes its associated base unit log interval.

Temperature Logs

Data packets received from the senders can arrive in any order at any time so they are accumulated in an array until the program is ready to plot them. A standard 10 second temperature graph plot interval is used to be able to combine and compare temperature logs with different log intervals from different TempLogger versions.

TempLogger™ Version 4.6 released
The latest version of TempLogger has been released, which has a new alarm timer and relay timer that were requested by clients. Our client base is growing steadily and TempLogger is now installed in 24 countries around the world.
Alarm Timer
A timer can be set for each of the 6 alarms as a failsafe precaution against temperature monitoring channel probe malfunctions. The time can be set for each step of the moulding cycle i.e. time in the oven and time in the cooling bay.
Relay Timer
Controlling rotomoulding machines is now even easier with TempLogger. When an alarm is activated, one of the 6 relays is latched, providing +24V DC to one of the connector poles that can be used to override any of the PLC timers. The resetting of alarm relays can be controlled manually or automatically by selecting a reset delay from 1 to 10 seconds. When an alarm is triggered, relays will remain latched until the Reset button is pressed or the reset delay time has expired.

TempLogger™ Version 4.4 released
Roto Solutions is continuously striving to improve the performance of TempLogger and the latest version has significant improvements to the Base and Sender units.
The Base unit
TempLogger V4 Base unit
The Base unit can be interfaced with rotomoulding machines to optimize machine operation. Internal mould and oven temperatures are used to trigger alarms that activate any one of 6 relays that can be connected to the PLC via an 8-pole, 5A cable connection.
Alarm Settings
The alarm settings define what recipe will be used and which relay will be activated. Alarm settings are used to control oven operation and cooling cycles and can be monitored for any one of the four available channels. Temperature readings are filtered to remove erroneous information such as spikes caused by probe malfunctions, before any alarm can be activated. As a failsafe precaution, any channel can be selected to monitor temperatures during a production run to prevent losing an expensive product.
When an alarm is activated, one of the 6 relays is latched, providing +24 V DC to one of the connector poles that can be used to override any of the PLC timers. There is no fixed way in which the relays can be connected to the PLC as they differ for each machine. It will be best to contact Roto Solutions so that a solution can be found for any particular interface.
The Sender unit
The performance of the Sender unit has been improved significantly. Each unit has a unique ID and can be set up remotely via radio signal in place of using a RS232 connection.

TempLogger™ Version 4.0 released
Roto Solutions has released their latest version of TempLogger 4.0, which has a new alarm monitoring interface and improvements to some components that were requested by clients.
Alarms Monitor Interface
Click here for a demonstration
The alarm monitoring interface provides a way for rotational moulding machine manufacturers to seamlessly interface their Windows based systems with TempLogger™, to replace timer based heating and cooling cycles with temperature based alarm monitoring, regardless of the machine configuration.
The interface is an ActiveX component whose purpose is to provide asynchronous notifications to a client application. The machine manufacturer’s system or client application can go about its business while the TempLogger™ component works on a task or watches for an occurrence of an alarm being activated.
Alarm Settings
TempLogger ™ alarm settings control oven operation and cooling cycles based on internal mould temperatures.
It is totally flexible how alarms can be configured, as there are no fixed rules. In general, the heating cycle and cooling cycles can be controlled by switching off the burner, opening oven doors and switching fans or water sprays on and off. For multiple skin moulding, alarms can be set to control the heating cycle for each material dump. In addition, a delay can be set for any alarm to prevent it from activating prematurely.
Client Application
The client program is set up to receive alarm activation events from TempLogger ™ and to send start and stop temperature log notifications to TempLogger ™ to control each cycle.
Setting up the client application to receive the alarm activation events is not difficult and a step by step procedure to walk you through the set up is available from Roto Solutions.
