Leon,
Do you remember the connection that you use when test the RS485-Fiber converter? They have 3 terminal screws. one (+), one (-) and the last one is marked with (C). I don't know if the C should be connected to ground. I check the master T100MD connected directly to the H-slave and it works properly. But, when I try to connect them trought the fiber optic, they don't have communication however the Tx and Rx leds are bipping (on, off).
Philip.

Can I connect the server directly to the rs485 using a RS232-RS485 converter?
So, I could access directly to the H-PLC.
I changed the program at the master T100MD with the H-serie example that you have, but right now I don't have any communication. At the RS485-Fiber converter, I have only the TX led flashing, the RX led is off. is like the H-PLC is not responding.

Hi Leon,
I connected the rs485- optic fiber converter, that you check. I have this funtion.

'Map Relay 33-48 from Slave#2 (MO#3) to Relay 1-16 in Master
'-----------------------------------------------------------

C$ = NETCMD$(3,"@02RR04")      'Read Slave#2 relays 33-40
IF LEN(C$)=0 RETURN: ENDIF      'Not getting response
DM[100]=HEXVAL(MID$(C$,6,2))      'Keep the value temporarily.

C$ = NETCMD$(3,"@02RR05")      'Read Slave#2 relays 41-48
IF LEN(C$)=0 RETURN: ENDIF      'Not getting response
DM[101]=HEXVAL(MID$(C$,6,2))      'Keep the value temporarily.

RELAY[1]= (DM[101]*256)+DM[100]

But it doesn't change the status of the relay 1 at the master. When I monitor the master PLC, at the variable c$ some time shows me values like @02R004.
and the dm[100] sometimes change the value such as -6,4,-48.
I don't know how to solve this problem.

Do you know where can I find information about some special caracters that I can use with the LCD420?

I don't remember where do I find a table with some caracteres like CHR$(12)  No cursor at the screen.

Is possible connect the COMM1 directly to a Parallel com of a matricial Printer? If that is p[ossible, what is the correct wiring?

Technical support / DAC
« on: February 11, 2003, 10:54:49 AM »
Hi,
I want to control the speed of a motor using a AC inverter. The inverter has a 0-5V speed control, so I want to use the DAC output from a T100MD888. With the HMI the operator could change the speed. I'm saving the speed value (0 to 500) in a variable (D). I need that the 0-500 will be proportional to 0-5 VDC. How can I program the DAC?

I have two problems:
1. When I run the ExceLink without name, it run well. However,I created a file with the name RA2 at the FileService folder, so I put at the file name C:\Trilogi\TL5\FileService\RA2 and none at the sheet name. When I run the ExceLink, it shows me the error Unable to open file C:\Trilogi\TL5\FileService\RA2 .

2. Sometimes when I run the ExceLink, it send a Illegal Operation and this is the detail:
JAVAW caused a general protection fault

« on: February 17, 2003, 08:08:41 AM »
Since the barcode is a DCE device, I made the special cable that you show us at the manual. The PLC is reading some values from the barcode scanner, but it doesn't read the numbers 0,3,5,6,9 and letter D. Is there any possibility why it is happening?
I change the funtion
a$= input$(1)
if len(a$)>0
b$=a$
endif
setlcd 1,1, b$+" "
just to see the variable

Technical support / barcode readers
« on: February 17, 2003, 04:55:54 AM »
Hi,
I connect a barcode scanner to com1.
I use these funtions:
1. Funtion
setbaud 1,3
2. funtion
A$= INPUT (1)
A= VAL(A$)
IF A>0
B=A: ENDIF

The PLC doesn't show any information when I read the barcode.
The barcode reader has many configurations, so I don't know if some parameters have to be changed. This is how it is configuarated (none,9600,8,1,even,CR) the others are options.
HANDSHAKING ? NONE     RTS/CTS, ACK/NAK, Xon/off
BAUD RATE ? ? ? ? 9600        19200,4800,2400
DATA BIT ? ? ? ? ? ? ? ? ?8 ? ? ? ? ? ? 7
STOP BIT ? ? ? ? ? ? ? ? ?1 ? ? ? ? ? ? 2
PARITY ? ? ? ? ? ? ? ?even ? ? ? ? ? ? Odd, Mark,space,none
TERMINATOR ? ? ? ? ? CR ? ? ? ?none,cr/lf,lf,h tab,stx/etx,eot

I checked the barcode reader using the HyperTerminal and it read the value of the barcode.

How can I solve the problem?
If I want to use the COMM3, the only part that I need to change is the setbaud 3,3 and the A$=INPUT(#).

Philip.

Technical support / ADC VOLTS
« on: October 26, 2003, 06:30:52 AM »
HI,
I HAVE A T100MD1616, I'M TRYING TO USE THE ADC TO SENSE THE TEMPERATURE USING A THERMISTOR 10K @ 25 C.

I CHECK THE VOLTS AT THE +5 VOLTS AND IT'S ONLY 1.2 VOLTS. I ADJUSTED THE AVcc POT BUT IT ONLY CHANGES FROM 0.5 TO 1.2 VOLTS.
I DON'T KNOW IF I HAVE TO CONNECT THE 24 VDC FROM THE POWER SUPPLY TO THE +12 to 24 V DC INPUT THAT IS BESIDE THE A/D IO TERMINALS.

THANKS

Technical support / Re: How can I control Servo motor by T100M??
« on: January 25, 2004, 05:38:30 AM »
Hi,
There are many servo drives ( EMERSON,YASKAWA,.....) that you can send the parameters throughout the RS232/RS485 and after the servo drive has saved them, you can use an output from the PLC to give the start signal to the Servo Drive.
You can program the servo to run an especific lenght according to the parameters.
