Telmecanique PLC TSX-17 - Problem....

Hi all,

(Telmecanique PLC TSX-17 )
HEC-FX417-Schinider's 9-pin end was connected to IO extension port of PCL by mistake. The HEC was off and suddenly the plant got shutdown. PCL reads "MD".
No other indications appearing even after switching ON/OFF several times. Can any one pl guide what is "MD"? Is it possible to get PLC back into operation ? How? Is it possible that the memory got crashed ? Where I can get the software for this PLC if sw is crashed ?

The EPROM is PL-74V20. How to recover program from this?
No catalogue is available & where can I get a detailed catalogue ?

Can anybody provide the cable & connection details Pl.
