PLC Parameters

Settings

Port, Retries and Time-Out are the communication settings between U90 Ladder and the PLC. Click the Advanced button to view the advanced RS232 parameters.

The other settings in this box belong to your project, and relate to the M90.

Note that if Jazz 2 is selected in Hardware Configuration, there will be additional options for TCP/IP.

Unit ID

Note that by default, projects are defined as 'Stand-alone'. If you want to integrate your PLC into a network, you must define the PLC as a member of a network and assign it an ID number.

Click Get to retrieve the ID number of a directly connected PLC.

Click Set to change the ID number.

Commands

To display information about the PLC connected to your PC, whether directly connected or within a network, click Get Version.

You can also view the current time and date settings within the PLC by clicking Get Time & Date, or import your PC's settings by clicking Set Time & Date.

You can also click on Reset to initialize the PLC, and click on Clear MB & MI to initialize values.

Advanced Settings

Click on Advanced. The PLC Communication Parameters box opens as shown below.

U90 RS232 Parameters	These settings are part of your U90 project. If you need to modify the default settings, click on the arrows to reveal the options. If this project is defined to 'Use Modem', we recommend that you change these settings to match the settings of the modem. If this project is defined as 'Use SMS', we recommend that you enter the settings of the GSM modem.
Force PLC Settings To:	This is checked by default, making the settings that you have selected become part of your U90 Ladder project. These settings will be installed in the M90/91 whenever communications are activated, overwriting the previous settings. Note that this does not write settings to Jazz controllers.
Restore Defaults	Click this to restore defaults
Get GSM Defaults	Click this to enter the settings used to communicate with standard GSM modems.
Set PLC Settings	Click here to write your selected settings into the M90/91. Note that this does not write settings to Jazz controllers.
Advanced	RS232 Time-Out settings may be edited. Make sure that the CANbus baud rate is the same for all networked M90 units.
Current PLC Settings	Click to retrieve the settings of the PLC to which you are directly connected. Note that this option does not work if you have defined the project as a network project.
