Hi Thomas,

Of course, you must say me after, sorry Thomas.

Well, a good notice, visual runs with allen-bradley, we attach you a
capture screen. Before, we comment you about some data, but, it is
beautiful, do you?  :-D

Yes, i have it

Yes, it runs perfectly.

Well, i aknowlegde that 1.set is for HMI, is it?

Ooopss! This is certainly! We are really silly, we must revised very 
more documentation.

I revised visual output, this is clearly from this:

Allen_B  : thread starts.
Allen_B  : driver instatiated.
setPort : /dev/ttyS0 rest 19200 n 8 1
setPort : /dev/ttyS0 = 6
setPort : fcntl: Success
setPort : tcget...:Success
setPort : 19200 rest n 8 1
setPort : n rest 8 1
setPort : 8 rest 1
setPort : tcflush:Success
setPort : tcset...:Success
Allen_B  : intSetup fd: 6
plcdrv  : load from ab.tfi
Allen_B  : comment        :Nuestra primera prueba
Allen_B  : condition      :A1 Allen_B  : CMD                :15
Allen_B  : FNC                :162
Allen_B  : type           :89
Allen_B  : File           :0
Allen_B  : first word     :100
Allen_B  : length in bytes:20
Allen_B  : sheet          :1
Allen_B  : to Cell        :B1
Allen_B  : Errors to Cell :E1
Allen_B  : comment        :Segunda prueba
Allen_B  : condition      :A1
Allen_B  : CMD                :15
Allen_B  : FNC                :162
Allen_B  : type           :89
Allen_B  : File           :7
Allen_B  : first word     :200
Allen_B  : length in bytes:20
Allen_B  : sheet          :1
Allen_B  : to Cell        :G1
Allen_B  : Errors to Cell :E2
engine   : no classname found
cellList : registrations:   0
plcdrv  : enter exec list
plcdrv  : enter exec TI1
Allen_B  : 6 execTI CMD f FNC a2
Allen_B  : 6 execTI p.t.r.i.w.3.b.a.f
Allen_B  : 6 I calc: eba1 = 161,235.

Well, how you can see, we modified ab.tfi, here it is:

<ALLENB> 'Nuestra primera prueba' 15 162 137 0 100 20 1 'B1' 'E1' 'A1' 
</ALLENB>
<ALLENB> 'Segunda prueba' 15 162 137 7 200 20 1 'G1' 'E2' 'A1' </ALLENB>

We see something in these test, but File... we don't aknowlegde at all, 
tomorrow we will fight with him more.

There are no difficulties, visuals runs at first time, only a despist, i 
edited S5 line instead allen bradley line, but in few minutes we see my 
error  ^_^

Well, i say you that we don't aknowledge this at all, for example we are 
used a counter for N10 but if we charged N10 we don't apreciated some 
changes in values showned by visual.

In capture attachment you can see that values for N7 and N0 practically 
are the same, only changes one cell, any explained?

Well, tomorrow we depurated our program for adjust it to integer values. 
Tomorrow we tell you.


More,

Well, how you can see, we modified for 19200, if value don't modified 
visual don't communicated with PLC.

But, we can't understand hardware handshake, we don't know where disabled.


More, we saw that you modified visual web page, and added spanish 
version. We send you pages when i traduced more. We saw too that faq are 
revised, there are some questions and answer, this is good, the project 
go on  ;-D

Well, we had it  :-DD
