I want to be able to use a 3rd party device to read the IO modules from an SLC505 without the use of the CPU. All the communications modules i come across appear to require the use of the CPU to pass thru the data.
MODULE Slot4 (Parent := "SLC_Adapter",
ParentModPortId := 1,
CatalogNumber := "1746-OW16",
Vendor := 1,
ProductType := 116,
ProductCode := 41,

KeyMask := 2#0000_0000_0001_1111,
SafetyEnabled := 0)
ExtendedProp := [[[___<public><PL>02<Version Name=$Q2.13$Q/></PL><CatNum>1746-OW16</CatNum></public>___]]]
ConfigData := [8,4,4,0];
ConfigScript (Size := 84) := [78,0,0,0,4,0,0,0,0,0,0,0,0,0,0,0,62,0,0,0,7,1,0,0,0,3,0,0,0,12,0,0,0,1,0,29,0,0,0,2,0,0,0,0,0,3,2,0,0,0,0,0,0,0,32,0,0,0,2,0,0,0,2,0,0,0,34,0,0,0,16,0,0,0

I think you are over estimating my ability Ken. But I keep learning by reading your posts in PLCTalk. I appreciate very much your input. For example, it did not occur to me the other day exporting the LK5 file, and I was trying to decode the forward open request after getting a Wireshark trace.Alfredo is probably the PLCTalk forum member with the most direct experience using CoDeSys with 1734 POINT.
I think I'm in agreement with your decoding! I'm leaving for the weekend so I'll get back to it Monday and hopefully our module arrives so I can quit probing this CPU and get to the fun stuff!!
Thanks again.
