Reading a value from a matrix (bidimensional array) of STRING_8 cause the write of truncated string on plc

[bombjackit]

Describe the bug

In Eth IP In, reading 2 tags of type STRING_8 in a matrix (10,2), x in the example belowe, cause the rewrite of the smaller string in the plc.

For example, I read x[0,1] (value "AABBCC") and x[0,0] (value "DDEEFFGG") : at first read of x[0,0] assume the value "DDEEFF" (it was write on plc), I have noted that has same lenght of x[0,1].

Expected behavior

Eth IP In must not write data to plc in any case

Going deeper on this issue, I discovered that if I read tags of type STRING_8 I had the same problem (not only inside an array but single tag) : maybe there is something correlate to the order of inserted tags inside the configuration (like #41)
