[EXL-CABxx cable]

I Need a New EXL-CABxx cable. In a hurry. Can I make one myself? Wiring diagram. Only for testing purpose while waiting for new

 

 

[EX-RC1 and V200/18-E3XB/I/O-expansions]

My customer want more I/O in my project. It started with V200/18-E3XB and have now 7 I/O expansions. Now he want another 7 temperature measurements and I do not have room for this in the cabinet. Can I use EX-RC1 and an I/O-expansion on the already configured system and put this remote? I get a warning when I try to define EX-RC1 in the project.

 

[Can i use same direct coil in different nets?]

only last net will apply, so no

[Drive error]

I try to install Visilogic on my drive, but get "catastophic error"

(Windows 10 Home)

It seems that the installation program try to install on G: instead of C:

Any solution?

[GPRS webserver]

I am trying to set up a connection with a webserver over GPRS. I have a DNSserver set up to connect the PC and Unilogic PLC, but can not reach the PLC. Over ethernetconnection it works perfect.

Any suggestion? I can send emails and the enfora modem receive GPRS IP

[SMS where the first part is the same, the last part changes]

I have a project that receive a SMS of this type:

 

FIRE at Station 2 Time 11:11.11

 

FIRE at Station 2 Time 12:11.12

 

The first part is constant, but the last part changes.

 

Can this be received by V570 and used to trigger a MB ? The message Fire at Station 2 shall open a valve fully open.

 

 

 

 

[Basic Issue with ladder program]

Or you can use M-contacts and OR them to the coil later in the program. When you use it your way, it is always the last used network that decide the coilstaus.

As UniGuru say, this is general to all PLC-manufacturers

[Current output from V200-18-E1B when PLC is in STOP]

Lawry: if I monitor the plc in stop mode, it shows 4095.

Joe T: I will try that. Thank you.

[Current output from V200-18-E1B when PLC is in STOP]

One instance is when downloading new program. Normally is not a problem, and if it is a system definition, I must live with it. But I had a hope that the output should be able to control as long as the MI-value is correct.

[How do I get around this one!]

Sorry, late answer. I do not know if I can repeat it. It happened when I quitted Visilogic accidently without giving arguments to the Block. The program was running on Win7 and I used V9.7.0 Visilogic.

[Current output from V200-18-E1B when PLC is in STOP]

I have a problem with a valve control. The controlsignal is 4-20mA. The control works very good when PLS is running.4-20mA give  decimal values 820-4095 on output. If I switch off the PLS, there is of course no value on output that is recognized as control signal by the valve, and it does not move (error condition on 4-20mA signal say that valve shall be in last position).

 

The problem is when the PLS goes to STOP, the value on the PLS Memory Integer is still 4095 (fully open valve), but the output from V200-18-E18 give an output the the valve control read as GO tO 0% (closed posistion).

 

Any idea what to do to get around this?

[PLC Idle stop ?]

Thanks!

I learned a lot here! Will try this and report back

[PLC Idle stop ?]

[PLC Idle stop ?]

I have a 570 with some hickup. Sometimes it stops: Status Stop - Idle with Fatal error, Ldr #68. The desription varies.I have tried to make a watchdog with a circuit that restart the PLC when this error occur, but have not suceeded. I try to use an output that when it falls the restart ciruit is ativated, but the output will not fall when the error occur. Is there an SB that is set or reset when this type of error occur? Or do anyone have a solution on the original problem?

 

[4-20 mA problem with impedance or generic problem?]

Hello. I try to use an Unitronics V200-unit (on a 570) 4-20mA output to operate a Samson 4-20mA-operated positioner. To start this positioner I must have 5 V across input (-impedance). When I use a Fluke 4-20mA simulator these 5V is generated at 3.8mA. When I connect the V200 to the positioner I must send between 8 and 9 mA to aquire the same 5V. This is a big problem!! Can anybody tell me how to solve this?

[PLC error]

I have V570. It stops after 2-3 days with the following screen

V290/V570 (T20B)

Is this meaningful?

[Enfora and 350/570]

OK now. Thank you

[Enfora and 350/570]

Is it not possible to use Enfora with V570 or V350?
