Richardc Posted June 3, 2019 Report Share Posted June 3, 2019 Hi, I'm new to UniLogic however seems to be very good software. I'm in the middle of a project where we are using UniLogic & MQTT to manage a heating/cooling system. So far i have been able to send and receive messages perfectly however I'm having some difficulty in sending a negative number from MQTT broker to PLC ( MQTT client). When it receives the message it sets the value to 0. I'm able to set the number box to a negative though the "Pop up" number pad on the touch screen. Does any one have any ideas on where i may be going wrong. Link to comment Share on other sites More sharing options...
NoamM Posted June 3, 2019 Report Share Posted June 3, 2019 Hi Richardc,Can you share a small project that demonstrates the problem? Link to comment Share on other sites More sharing options...
Richardc Posted June 6, 2019 Author Report Share Posted June 6, 2019 Hi NoamM, Thanks for the response. I am unable to create a new project as it needs all the MQTT bits creating also. However i have solved my Issue. For some reason if i use a INT16 type number field it works fine however if i try to use a INT32 number field it doesn't so i have just changed it to INT16 as that covers our requirement.
