RS485 connection

The RS485 connection of the UMG507 is designed as a 9 pole Sub D sleeve. We recommend a 9 pole Profibus plug

for connection (Type: SUBCON-PLUS-ProfiB/AX/SC Producer: Phoenix part.No.: 27 44 38 0 or comparable).

Connection of the bus cables:

Connect the incoming bus cables always to the terminals 1A/1B (Also at the beginning of the bus system!) The

outgoing bus cable is connected to the terminals 2A/2B. The terminal resistors are activated via the slide switch at

the beginning and end of the bus system. The terminals for the outgoing bus cable (2A/2B) are disconnected

simultaneously.

Application 1: Energy rates

.Task: Real energy consumption shall be counted in different rates according to the respective daytime. The rate times

have to be programmed for winter and summer time separately. The place of installation is IRAN.

The following times have been fixed:

Summer time: Winter time:

Tariff 1 (T1) from 00:00 - 10.00 h Tariff 1 (T1) from 00:00 - 12.00 h

Tariff 2 (T2) from 10:00 - 24.00 h Tariff 2 (T2) from 12:00 - 24.00 h

Energy meter T0 is the addition of T1+T2.

Strategy:

1. Fixing of the time zone offset

2. Programming of the weekly switching clock for the corresponding tariff times

3. Programming of the time zone comparator

4. Programming of the logical combinations

5. Fixing of the I/O configuration

Step 1:

The time base of UMG507 is based on UTC. The standard time in Iran is GMT+3,5h for winter time and GMT+4,5h for

summer time. This corresponds to a time zone offset of 12600sec in winter and 16200sec in summer.

The summer/winter time changeover in Iran is as follows:

Winter/summer time changeover = First day in Farvardin

Summer/winter time changeover = End of 30th day in Shahrivar

This means, a calculation from the Persian calendar to the Gregorian calendar must be carried out.

The changeover according to the Gregorian calendar would be:

Winter/summer changeover = Third Monday in March at 23:59h (20:29 UTC)

Summer/winter changeover = Third Wednesday in September 23:59h (20:29 UTC)

Those data can be programmed via PSW.

Step 2:

Programming of the weekly switching clock channels

Switching clock channel No.1 (for summer Tariff 1) Switching clock channel No.2 (summer Tariff 2)

Weekday first : Monday Weekday first : Monday

Weekday first : Sonday Weekday first : Sonday

Hours: 00:00 Hours: 10:00

Minutes: 10:00 Minutes: 23:59

Switching clock channel No.3 (for winter Tariff 1) Switching clock channel No.4 (winter Tariff 2)

Weekday first : Monday Weekday first : Monday

Weekday first : Sonday Weekday first : Sonday

Hours: 00:00 Hours: 12:00

Minutes: 12:00 Minutes: 23:59

Programming of the function combinations in

panel „Logic operations for maker flags“

Step 3:

Programming of the time zone offset comparator.

The UMG507 saves the actual time zone offset on address Adresse 7194. This offset is 12600sec during winter and

16200 sec during summer. The comparator contains the actual status after programming. If the time zone offset is

> 12600sec the output of the comparator is active.

Input parameter 7194 .

Step 4:

Programming of the logic.

In the logic is checked, which switching clock channel is active, and if it is summer or winter.

The combinations would be as follows:

Time switch channel 1 AND Comparator 1 = Flag 82 //Summer Tariff 1

Time switch channel 2 AND Comparator 2 = Flag 83 //Summer Tariff 2

permanent active NOT AND Comparator 1 = Flag 84 //Inverting comparator

Time switch channel 3 AND Flag 84 = Flag 85 //Winter Tariff 1

Time switch channel 4 AND Flag 84 = Flag 86 //Winter Tariff 2

Flag 82 OR Flag 85 = Flag 87 // Result Tariff 1 Active

Flag 83 OR Flag 86 = Flag 88 // Result Tariff 2 Active

Programming of the function combinations in

panel „Logic operations for maker flags“

Step 5:

Programming of the output configuration

The flags are assigned to the energy meters in the I/O assignment.

Programming of the

function combinations in

panel „Output channels“

Step 6:

Check functions

The function check can be carried out via the display of the UMG 507 or aided by PSWprofessional. In PSWprofessional

the topology is used for that purpose. All actual flag and switching clock conditions are displayed here.

Use right mousekey on the device in topology

and select function “show all measured values“.

The topology must be „online“.

One more possibility is to drag all important parameters into the display of UMG507.

The following parameters are useful:

Time channel 1 = Parameter: 3296

Time channel 2 = Parameter: 3297

Time channel 3 = Parameter: 3298

Time channel 4 = Parameter: 3299

Comparator 1 = Parameter: 3320

Flag 82 = Parameter: 3360

Flag 83 = Parameter: 3361

Flag 84 = Parameter: 3362

Flag 85 = Parameter: 3363

Flag 86 = Parameter: 3364

Flag 87 = Parameter: 3365

Application 2: Email for short interruptions

Task: An Email must be sent after a trigger event (e.g. short interruption). The email shall transmit the starting and

ending time of the short interruption. Starting and ending time shall be deposited in the parameter memory additionally.

The status of the short interruption must be provided on a digital output.

The following conventions have been made:

1. Digital output 1 active = Short interruption active

2. Digital output 1 chopped = Short interruption was active

3. Digital input 2 resets the status of the digital output

Steps:

1. Input DNS address.

2. Email configuration.

3. Fixing the limits.

4. Programming of the logical combinations.

5. Fixing of the I/O configuration.

Step 1:

Enter the IP address of your DNS servers first.

Please ask your system administrator for the

corresponding settings.

Step 2:

For the Email Account configuration, you need

the following data from your system

administrator

1. Server name = Post output (SMTP)

2. Account name

3. Password for your Email account

4. Authentification (Login, Plain, Cram-MD5)

5. Email address of UMG507 (Mail from)

6. Subject

5. User address

Note:

If several recipients must receive the same

email, the email adresses must be separated

by a semicolon.

Example:[email protected];[email protected]

The following short descriptions are entered within the Email text (see address list):

<ul1min> = Minimum value of voltage in phase L1.

<ul2min> = Minimum value of voltage in phase L2.

<ul2min> = Minimum value of voltage in phase L3.

<tsu1minon_s> + <tsu1minon_m> = Start of short interruption in UTC time (Seconds + Milliseconds).

<tsu1minoff_s> + <tsu1minoff_m> = End of short interruption in UTC time (Seconds + Milliseconds).

The short interruptions are set to the actual values while creating the email. The minimum values have the average of

10 periods. More exact data are saved in the trigger memory (True RMS values over 128 periods) and can be read with

PSWbasic/professional. If the clock of the UMG507E/EP is synchronized by a NTP Server, the accuracy of the time

is about10 to 20ms. Three emails are required.

Email text No. 1 for phase L1: Email text No. 2 for phase L2:

L1 <ul1min> V L2 <ul2min> V

L2 <ul2min> V L3 <ul3min> V

L3 <ul3min> V L1 <ul1min> V

from <tsu1minon_s>sec + <tsu1minon_m>ms from <tsu2minon_s>sec + <tsu2minon_m>ms

to <tsu1minoff_s>sec + <tsu1minoff_m>ms to <tsu2minoff_s>sec + <tsu2minoff_m>ms

Email text No. 3 for phase L3:

L3 <ul3min> V

L1 <ul1min> V

L2 <ul2min> V

from <tsu3minon_s>sec + <tsu3minon_m>ms

to <tsu3minoff_s>sec + <tsu3minoff_m>ms

Step 3:

Fix limits for short interruptions for each phase in window

„Short interruptions / Overcurrents“ .

Low voltage phase L1

Low voltage phase L2 Low voltage phase L3

Saving the true RMS values

within the trigger memory.

Step 4:

In window „Logic“, the functional combinations are programmed.

No.: Source 1 Operator Source 2 Target flag

5 Permanently inactive AND Permanently inactive = 84

6 Short low voltage UL2 Neg. edge Permanently active = 84

7 Permanently inactive AND Permanently inactive = 85

8 Short low voltage UL2 Pos. edge Permanently active = 85

14 Short low voltage UL2 Pos. edge Permanently active = 89

15 Short low voltage UL3 Pos. edge Permanently active = 90

16 Flag 91 XOR Permanently active = 91

// By this assignment, the flag flashes cyclically every 200ms

17 Flag 88 OR Flag 89 = 92

18 Flag 92 OR Flag 90 = 93

// if short interruption is active in one phase, flag 93 is set

19 Flag 93 AND Flag 91 = 94

// if short interruption is active in one phase and flag 91 is active, flag 94 should flash

20 Flag 94 OR Short low voltage UL1 = 95

21 Flag 95 OR Short low voltage UL2 = 96

22 Flag 96 OR Short low voltage UL3 = 97

// the flag is active while short interruption and flashes after short interruption

23 Digital input 2 Pos. edge Permanently inactive = 88

24 Digital input 2 Pos. edge Permanently inactive = 89

25 Digital input 2 Pos. edge Permanently inactive = 90

// Resets the flashing

Description of the flags (only for information):

Flag 82 = Send Email No. 1 when short interruption L1 ends.

Flag 84 = Send Email No. 2 when short interruption L2 ends.

Flag 86 = Send Email No. 3 when short interruption L3 ends.

Flag 82 = Save parameter 5139 (time of short interruption L1 Stop)

Flag 84 = Save parameter 5145 (time of short interruption L1 Stop)

Flag 86 = Save parameter 5151 (time of short interruption L1 Stop)
