16 February 2020 - 08:44 AM





For fixed speed applications, provided that the fixed speed is equal to the line speed, there will not be energy savings when a VFD is used compared to a soft starter.

Sending Sms Text Messages With Xl4 On Gsm

07 September 2019 - 12:53 AM

GSM networks are being closed down in many countries.

Here in New Zealand, 2Degrees have closed down their GSM network, Spark never had one but Vodafone are suggesting they will hold the GSM network till 2025.


Sending SMS messages on an XL4 on the GSM networks, requires that the firmware is equal to or less than 14.16


It appears that SMS messaging on the XL4 on the GSM network has been disabled above firmware 14.16

Firmware above 15.00 seems to support SMS on the 3G network only.


This has been tested on both internal and external modems.


Best regards,


Trig Functions In Iec Programming Languages

05 June 2019 - 10:09 AM



Got caught a good one this week,

A GPS angle calculation would not work correctly, but eventually came to the conclusion that the SIN and COS functions are radian based, not degree based.

The advanced Ladder option includes both radian based and degree based function blocks.

So far, I have no found a "degree" option in the trig functions.
