Initialize Com port 1
Jas replied to Wambo's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
This poster is correct. As of recent, Vision controller operating systems now mandate the use of 9600 baud rate for the Enfora modem. It used to be the case that any speed would work, and actually 57,600 was the most common to use. This is no longer true, and you must re-prepare the PLC side modem for a 9600 baud rate as well as have this set in the COM Init function block. -
expansion error

Unfortunately no, a crucial part of the improved system is the new cable. -

The main advantage of the EX-A2X is the much improved isolation. The "upgraded" EXL-CABxxx cable is required in conjunction with the module. -
Previous version 9.3.0

This will be active for a little while longer, until the new link is offically added to the swapper page. http://www.unitronics.com/Data/Uploads/VisiLogic_Software_New/VisiLogicSetup_930.exe -
There is no direct option to enter memory floats via keypad entry on standard series vision controllers (V120, V2xx). A workaround would be to enter the value into a memory integer register and then via ladder logic convert that to a memory float. Please see the attached example that does exactly this for one decimal place of accuracy (4.1 base format). Also, do you really need to use a memory float though? Another option would be to just keep track of that tens place (one decimal) offset in any math or logic operations you may perform while solely using memory integers or memory longs.

Enfore Modem Problem - No Carrier
Jas replied to Michael's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Yes, this is its intended purpose. From VisiLogic you would select "TCP/IP Call" as your connection method to target the IP address of the SIM card. You can then go into "online test mode" to troubleshoot and debug. -
Enfore Modem Problem - No Carrier
Jas replied to Michael's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
I have never seen a "pure" data call work on US carriers as of recent. The best method would be to use GPRS data to transfer your information. Please note this will not be lightning fast, but does work. It also helps if you obtain a static IP address from AT&T. Otherwise you are assigned a different dynamic IP each time the SIM card registers on the GSM network, and often useful ports are blocked. We do have a webinar detailing GPRS communications as well as a sample project if you are interested. http://forum.unitronics.com/index.php?/blog/15/entry-61-webinar-modems/ -
Change in HW Configuration
Jas replied to janm7462's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Unfortunatly, there is no simple re-sizing tool available. As i'm sure you have noticed, the smaller resolution (320x240px) V570 screen is placed in the upper left quadrant of a new project after converting to the larger resolution (800x600px) V1040 screen. -

Vsilogic 9.3.0 Error
Jas replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Please see the document in the pinned topic for Windows 7 http://forum.unitronics.com/index.php?/topic/664-can-i-use-visilogic-with-vistawin7/ -
There's no straight forward way to clear the logs. One option is to use the "Enable Auto Logs Purge" feature. This is found in the site configuration options.

Please see the attached program. This function is linked to HSC0 (I0), set as High Speed Counter. It gives the pulse frequency in DW0 with resolution and precision of 0.01 Hz. As a demonstration, the HSO of the snap-in can be connected to the HSI as defined in the HW config. V570 - HSC Frequency Measurement.vlp
