BC820 RCU link cable 200m connection
Dear sir,
In the catalog, it is described below regarding BC820.
-------------------------------------------------------------------
BC820K02 RCU-Link and CEX-Bus Interconnection Units Allows AC 800M redundant PM858, PM862 or PM866 pair to be up to 200 m apart, cables not included.
-------------------------------------------------------------------
Regarding "pair to be up to 200 m apart", how can be this done? TK857 is only 0.3m.
I cannot find any accessory for this. Please share your solution.
Thanks.

Hello,
TK857 is RCU link cable that connects CPU's RCU port to it's own BC820's RCU port, As both are connected on the CEX bus already, this doesn't require muck longer cable.
The connectivity between 2 BC820 is what extends to 200m range and 2 BC820 are connected together by 2 cable "RCU control ink cable" which is a normal full crossover cable and other is " RCU data link cable" which is an optical cable. both these cables are available from multiple vendors with variable lengths and quality.
For more info see "3BSE036351-610_A_en_System_800xA_6.1_AC_800M_-_Controller_Hardware" Page 103 section 2.9.1
I hope this information helps.
Best Regards
