Technical support / Re: PLC stops triggering relays after 2 min.
« on: January 07, 2004, 11:05:18 AM »
An email has been sent advising you on the procedure of checking as well as return address if it is a faulty board. Please respond to the email.

Technical support / Re: Comparing counter values
« on: January 09, 2004, 06:03:29 AM »
This would be really easy on a M-series PLC. Unfortunately, the H-series ladder language does not support a counter compare function. However, if the counts are less than 32 then you could use the sequencer step to trigger action when two sequencers reaches the same step (i.e. same count). For larger count there is no available command.

LDHEX is only available on E10, not on the H-series.

Technical support / Re: MD-HMI LCD problems
« on: January 12, 2004, 08:37:03 AM »
The booster board boost the signal for the expansion port but not the LCD port. It was used mainly for interfacing the HMI to older generation of T100MD+ PLC and may not be helpful in this case.

You do need to tackle the origins of the noise source. It is likely to be caused by noise from inductive kicks. Try to add diodes or transorb to your output if you are driving inductive loads such as solenoid, contactor or motors. Also make sure that the LCD cable is not "bundled" with any 24V or 120V in the conduit as the 5V signal to the LCD can be affected by high current in such wires.

Technical support / Re: Sharing up/down keys
« on: January 12, 2004, 08:56:34 AM »
In our SetTimeCtr_SV example we use one key ("select" input) to select up to 6 parameters (3 timers and 3 counters) - you can do the same here. Just one set of up/down keys and 1 select button.

If you have the HMI, it seems to make more sense to me to use the keypad to enter your values instead of up/down key. In this case, just use a function key (say F1) as the select key to select different parameters (show the chosen parameter on the LCD), then use the numeric keypad to enter the data.

Technical support / Re: MD-HMI cursor blinking
« on: January 16, 2004, 11:27:26 AM »
Please refer to your PLC's Installation guide on using the SETLCD command to change the cursor shape (block or underscore), blinking or static or ON or OFF.

Technical support / Re: Scrolling Text on 4X20
« on: January 19, 2004, 08:49:28 PM »
You will have to define your menu structure in software. There isn't a command for scrolling the text since there isn't buffer to store text that are "off the screen". If you want to display more than 4 lines, then implement a "page up" and "page down" using the function key. Use a variable to keep track of the page number and then display the corresponding text to the page.

Note that since the string A$ to Z$ an also be represented by an array $$[1] to $$[26] you may be able to store some text in the string variable and selective display them using the index n to the array $$[n].

Technical support / Re: Modem Communication
« on: January 19, 2004, 08:52:29 PM »
You have to put your modem in "Auto Answer" mode so that when you PC dial your remote modem it will answer the phone and then connect itself to the modem. See the "Appendix 3: PLC to Modem Communication Setup" in your Internet TRiLOGI reference manual for more details.

Technical support / Re: PLC + GSM
« on: January 20, 2004, 06:12:21 AM »
The T100MD+ PLC is very flexible in what it can send or receive from its serial port and therefore the choice for connecting via a modem.  Although we have no experience with the particular brand of GSM modem you mentioned, there are customers who had successfully used the GSM modem with the PLCs.

Technical support / Re: HSC + Encoders
« on: January 20, 2004, 02:26:19 PM »
The HSCs count every incoming quadrature pulses. It is not true that it counts one in four transitions. It determines the direction of counts based on the phase differences between the two inputs. If you have enabled the enhanced quadrature counting then the B phase must transit in proper relation to phase A in order for the count to be recognized.

We haven't been able to find such LCDs that support standard 14 pin LCD pin out. We would like to hear whether other users have some experience to share.

Technical support / Re: How can I control Servo motor by T100M??
« on: December 27, 2002, 08:03:24 PM »
Check with your servo motor supplier for a servo driver that accept pulses and direction input as if it is a stepper driver. You can then use the PLC's stepper output to drive it.

Technical support / Re: How can I control Servo motor by T100M??
« on: November 01, 2002, 10:03:56 AM »
A T100M PLC only has 2 stepper controllers and it is not designed for direct interfacing to Servo motor and encoder. However, there are some servo driver on the market which act like a stepper motor and have the loop closed at the driver. These type of servo motor will accept pulse and direction inputs from the PLCs. Such servo motor can be used since to the T100MD they are just like stepper motor even though these servo drive are really closed loop system.

Did you download the International language version of JRE? We have given clear instruction that you should download the US English version of TRiLOGI. International version may not work properly. We only test our software with US English JRE 1.3.1 and English version of Windows. We are not sure if there are other compatibility issue if your Windows is other language version.

Technical support / Re: Active Server Page Control
« on: January 26, 2004, 04:44:12 PM »
The VB example accesses the PLC directly via the serial port. It is not network based and hence cannot be converted into ASP page. Currently we only support Java based applet with a Java API library.

Technical support / Re: thermal line printer
« on: February 06, 2004, 11:06:11 AM »
Did you try sending some data to the printer from HyperTerminal "Direct to Com x" configuration? That give you a better idea of how to get the printer to print out what you want.

If there is a DIP switch for XON/XOFF, then disable the XON/XOFF to simply communication.

The cable from PLC to the printer will be opposite that of the cable pin out from PC to the printer. Assuming your description of the pin out from PC to printer is accurate, then you should connect the following:

  PLC              Printer
    2                   3
    3                   2
    5                   7
    
Also short pin 6 and 20 together on the printer side. No other connection is necessary on the T100MD+ PLC side.

(Note that T100MX+ is different because it requires pin 4 to be connected to a +10V power to operate properly, usually this is obtained from the DSR pin of the host PC).
