Solution
Any Ethernet CompactDAQ can be included in a daisy chain of chassis. Many of the non-TSN Ethernet chassis (the 9188 included), only have a single Ethernet port. So while they can connect to a computer through a chain, there can only be a single chassis of this type and it must be the last chassis in the chain, for example the cDAQ-9183 and cDAQ-9187.
Additionally, daisy chaining is primarily used to add TSN time synchronization functionality, and while these non-TSN chassis can be included in the chain, this does not give them access to TSN functionality. If a non-TSN-enabled device is placed between two TSN-enabled devices, it will break the chain and not allow them to synchronize via Time Sensitive Networks. If you would like TSN-enabled devices to synchronize, link the non-TSN-enabled chassis on the end of the chain.
