1. Delete MI 8 power-up value -Sample Time. It will be calculated by Autotune. 2. Water temperature range is 0 to 100. It is recommended to set: - MI 9 =0 (0.0) - MI 10 = 1100 (110.0) 3. MI 0 show temperature in 0.1 C/F. 4. Change User Set point MI 47 format to 4.1 Entering 55.1 from display will be represented as 551 in MI. 4. Use MI 47 instead of MI 3. 5. Sample MI 0 in 4.1 format. 6. Delete nets 2 and 3. Test it.

Hi, Jazz OS has no embedded support for Alarms. You have to realize it by yourself, or use other PLC model with embedded alarms support. It is recommended to review example projects to find one which fitting your needs. B.R.

Hi Drew, UDFBs are part of UniLogic Examples: https://www.unitronicsplc.com/software-unilogic-for-programmable-controllers/ Scroll down and download. B.R.

Visit next link: https://www.unitronicsplc.com/support-technical-library/ Expand required PLC topic and look for 2D/3D models: Tell us if you need anything else (support@unitronics.com). B.R.

Please forward your request to support@unitronics.com

Hi, Please send your request to support@unitronics.com, include PLC model and serial number. B.R.

Estimated Google translation: ----------------------------------------- Best regards. I am starting to use unitronics brand PLCs in version V1040 and I need the reading and writing registers between the drive and the PLC to be simultaneous, the communication is being done through MODBUS RS-485, I have the problem that the PLC is always sending the frequency register to write to the inverter, since the PLC receives a signal from a sensor, making feedback with the inverter, and for some reason this interferes with the other registers, so I cannot read more regi

Hi, PLCs are not intended to be NTP servers. You can Google for "local NTP server without internet" and select better fitting for you solution. B.R.

You use direct connection PLC to PC, Why you use Default Gateway D# 192.168.1.1 - it is from different network.

What is an IP address you send ping to? Is this IP inside or outside of your network? How you configured PLC OP, Mask, Gateway? Does your network require MAC address registration on DHCP Server and Domain Controller?

Review example from VisiLogic Examples: C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\Communications\Ethernet\ V700_Ping_Example.vlp * It is rfecommended to make Init to all sockets to defaults (see Help). Only change sockets with different configuration. Take care that "Ping" button is toggle. So in your test you have to activate MB 56 to see PING reply. B.R.

SB 350 description will be added to Help. Request sent to Help writer. B.R.

Some additional information: All referred in help and in this post PWM frequencies are for on-board and snap-in modules, direct connected to PLC CPU. Expansion modules has 1 Hz step, and you have to follow IO module specification. B.R.

Yes, Set Duty Cycle to 0 to have output OFF. B.R.
