[Function 'Copy Array Part to Array']

Hello Eyal,

 

It seems the function requires a UINT and will not accept an INT. That is why it was not offering my original tag - which was an INT - and also offering me some arrays I had created of type UINT.

 

I think we are systems go again, thank you.

[Function 'Copy Array Part to Array']

I 'm trying to use this Ladder Function to copy one array (of integers) to another. As I understand it, parameters A and B specifiy the source array and offset, parameters D and E specify the target array and offset, and parameter C specifies the length (no of items) to be copied. I would have expected parameter C to be an integer, but the compiler is demanding an array!

Have I misunderstood the function?

Understood, and thank you, Eyal.

[UniStream I/O Connectors]

Hello Eyal

 

The system we are building will have optionally 1 to 4 UID1600 IOs, each connecting to a separate DB-25 connection socket in the cabinet linking to the external equipment.

 

We wish to make a standard cableform that will link a UID1600 (4 sets of 4 digital inputs) to the D-type connector socket mounted in the wall of the cabinet holding the UniStream PLC. The cableforms will be assembled by an external supplier, to whom it would sensible for us to give a minimum order of 20 cableforms or so. This would be in advance of our ordering the UniStream UIDs themselves. To make the cables the supplier needs 20 x 4 (=80) UID connectors, as well as the D-type sockets which are readily available on the market. Are the UID connectors available separately?

 

I hope this clarifies a bit.

 

Regards

[Beginner Ladder Programming Question]

You can perform a comparison "pressure >= X", and if True then make a Return Call. No lower rungs in the ladder will be executed unless the pressure falls below X.

[Copy Array to a DTI column]

I want to copy from an Array (INT16 × 15) to a single DTI cell which holds a similar array. In effect I'm trying to copy one dimension to another.
Does the function 'Copy array to column in DTI' allow this? The compiler allows me to set the function up, but no data seems to be transferred.

Apologies if in the wrong forum.

 

I wish to have made cableforms to connect to UID-1600 devices we may supply as optional upgrades to the system we are manufacturing. The cableform will include the 7-way connectors (2-types) identical to those that you provide with this device, but I cannot at present find the exact part references. I believe they are made by Phoenix.

[Welcome!]

Thanks Joe. I guess that to read a temperature local to the controller - with no CANbus otherwise needed - my most cost-effective way would be to use a UIA-0402N with a 0-10V temperature sensor (e.g. EI-1034).

Apologies for probably being in the wrong forum, but what UniStream I/O should I use to read a thermocouple? Is therean equivalent to the VisiLogic IO-ATC8?
