Safety remote I/O module safety response time
The safety response time of the safety remote I/O module is shown below.
For the response time including the network delay time, refer to the following.
 Mitsubishi Electric Safety Programmable Controller MELSEC iQ-R Series Machinery Directive (2006/42/EC) Compliance
■Input
Transmission interval monitoring time  2 + Safety remote station input response time
■Output
Transmission interval monitoring time  2 + Safety remote station output response time
Transmission interval monitoring time
The transmission interval monitoring time is the time that the receiving station monitors in safety communications to detect the
following safety communication errors.
• Transmission interval delay of safety data due to an error in the sending station
• Loss of safety data in the transmission path due to influence such as noise
Configure the monitoring time in the module parameter setting on a module-by-module basis. For details on the module
parameter setting, refer to the following.
Page 72 Parameter Settings
Set a value that meets all the following calculation formulas for the transmission interval monitoring time.
• TM  SRref  2
• TM  SCmst  2 + LS  2
SRref: Safety remote station refresh response processing time (2.0ms)
TM: Transmission interval monitoring time
SCmst: Safety cycle time of the master station
LS: Link scan time
