Calculation of the response time in the case of the IM151-1 HIGH FEATURE
When you calculate the ET 200S response time, you have to choose between 2
setup variants:
1. If you only have power modules, digital electronic modules and motor starters in
your ET 200S system (exception:
no
motor starters; High Feature), use the
following formula:
Response time [
m
s] = response time
PII
+ response time
PIQ
+ 1000*
Response time
PII
[
m
s] = 55 · m +130
Response time
PIQ
[
m
s] = 10 · m
do
+90
2. If your ET 200S setup differs from no.1, the following formula applies:
Response time [
m
s] = response time
PII
+ response time
PIQ
+ 1000*
Response time
PII
[
m
s] = 55 · m +125 · ai + 175 · t +250
Response time
PIQ
[
m
s] = 10 · m
do
+125 · ao + 175 · t +130
Explanation of the parameters:
•
m
: Total number of all modules (power modules, digital electronic modules,
analog electronic modules, IQ-SENSE electronic modules, process-related
modules, and motor starters)
•
m
do
: Slot number of the last digital output module, 4 IQ-SENSE electronic
module, or motor starter in the ET 200S setup. You should place these modules
or motor starters on the front slots to improve the response time.
•
ai
: Sum of all analog output modules
•
ao
: Sum of all analog output modules
•
t
: Number of all process-related modules
•
*
: In the case of clocking, this value can be increased by configuration (settings
on the DP master system in HWCONFIG equidistant DP cycle). Note: This
value (1000
µ
s) must be included in the calculation even if you have not set
clocking.
