Description
(a) Safety
sensor/
switch re-
sponse
time This is the response time that is required for a safety sensor or switch, such as a light cur-
tain, to turn OFF. The value is defined for each sensor or switch.
Use the following values when an OMRON Special Safety Input Device is connected to a
Safety Input Unit.
E3ZS/E3FS Single-beam Safety Sensors
: 14 ms
D40A Non-contact Door Switches
: 6 ms + 0.4 ms x No. of linked Switches
*1
D40Z Non-contact Door Switches : 29 ms
UM/UMA Safety Mats
: 24 ms
*2
SGE Safety Edges : 24 ms
(b) Safety In-
put Unit/
slave re-
sponse
time This is the input response time required for a FSoE salve or CIP Safety slave, such as
Safety Input Units. A specific value is defined for each device.
The response time of Safety Input Units is as follows.
NX-SIH400: 9 ms + On-Off delay time
NX-SID800: 5 ms + On-Off delay time
For any other device, refer to the manual for the device.
(c) Network
reaction
time This is the response time required for the CIP Safety connections or the FSoE connections.
These values can be verified on the Sysmac Studio. For details on how to check the net-
work reaction time, refer to
5-4-2 Setting Up the CIP Safety Communications on page
5 - 13.
For FSoE connections: FSoE Watchdog Timer value
For CIP Safety connections: Network reaction time value calculated by the Sysmac Studio
(d) Safety
CPU Unit
response
time Response time of the Safety CPU Unit. This value is an integer multiple of the safety task
period. The value varies, depending on the safety chain route as follows.
When the FSoE connections are used for
both input and output
: Safety task period x 0
When the CIP Safety connections are used
for both input and output : Safety task period x 2
When the FSoE connections are used for in-
put and CIP Safety connections are used for
output : Safety task period x 1
When the CIP Safety connections are used
for input and the FSoE connections are used
for output : Safety task period x 1
(e) Safety
Output
Unit/slave
response
time This is the output response time required for a FSoE salve or CIP Safety slave, such as
Safety Output Units. A specific value is defined for each device.
The response time of the Safety Output Units is as follows.
NX-SOH200: 1 ms
NX-SOD400: 1 ms
R88D-1SN
£
: 4 ms
For any other device, refer to the manual for the device.
(f) Actuator
response
time This is the response time that is required for an actuator, such as a safety relay, to turn
OFF. The value is defined for each actuator.
*1. The fault detection time for a 24 V short-circuit fault in a D40A Non-contact Door Switch is 18 ms. If usage is
for an application other than a Door Switch, use a safety sensor/switch response time of 18 ms.
*2. Refer to Precaution for Conformance to ISO 13856-1:2013 on page 8 - 4 for a precaution on conformance
to ISO 13856-1:2013.
