*1 Modbus is a registered trademark of Modicon, Inc. 
*2 Can be changed by internal switch. 
*3 When the analysis option is added on VM-701B and/or VM-702B monitor module. 
*4 VM-7B can be controlled by the host computer.by adding the option. 
Note : The daisy chain connections are eight racks or less.

*1 About the Security Function  
 ・When selecting the presence of "security function", other networks (VM-741B:MCL View) to  
unify security policies are also " Please select the presence of security function " 
・"Security Function" is the network of "Fieldbus（Modbus/TCP）" and "Analysis software 
communication(TCP/IP) ".  
・Custom setup of "Security function" can’t be order. 
・Select "Security Function", you can meet a global certification program  
(Achilles Certification Level 2) that proves to have a certain network robustness. 
・Achilles is a registered trademark of GE Digital. 
1 SEC WAVEFORM DATA COLLECTION FUNCTION  
Sampling interval(VM-701B, VM-702B) : Waveform 
 : 1sec (Default value:10sec) -“1 sec waveform data collection function” is available "Analysis software 
communication (TCP/IP)" is specified. -“1 sec waveform data collection function” is available when "Security 
function" is "None".
