[Design Precautions] DANGER

The output may remain on or off the Mitsubishi Electric MELPRO-D Series Protection Relay (hereinafter referred to as MELPRO-D) has failure.

Provide an exterior circuit to detect output signals that may lead to a serious accident. Output error and malfunction may cause an accident.

If communication error occurs (including unexpected coming-off of a cable), the communication between MELPRO-D and the master station will be interrupted to make the communication functions inoperable.

When integrating MELPRO-D in your system, configure your system in such a manner that switching operations which are very important to the system will be given by other device, not MELPRO-D, on the assumption that MELPRO-D may have communication errors.

Output error and malfunction may cause an accident.

For what will happen to each station when the sequencer CPU stops computation or an update error occurs in the data link, refer to the chapter 5 Data link processing time in the Master Unit User Manual.

Configure an interlock circuit on the sequence program using the communication status information as below mentioned so that the system can operate on the safety side.

Output error and malfunction may cause an accident. -Data sent from the data link error station of the master and local stations: (1) Remote input (RX), Remote output (RY)

[Design Precautions] CAUTION

Do not bind communication cables together with the main circuit or power line. Also, do not install communication cables near the main circuit or power line. As a guideline, all the communication cables should be away from the main circuit and power line by at least 100 mm.

Otherwise, noise may be generated to cause malfunction. In consideration of the case of communication becoming impossible by noise etc, if response cannot

be found during a certain fixed time (10s), please clear transmitting information. It is necessary to notify then that it has not transmitted.

The relay might do the restart processing by the noise etc. An abnormality of data link is generated while

processing the restart. In this case, please install the timer of about one second for masking the abnormality

of data link signal from the relay. MELPRO-D always observes an electric circuit and a built-in power

supply. When abnormally generated, the operation output is locked, RUN display LED is turned off, and

self-diagnosis signal is output. However, the relay tries the recovery of protection function by the restart

processing which aims to prevent the output of self-diagnosis due to occur by the transient disturbance

such as noise. The communication function stop time during restart processing is 300ms or less.

The restart processing will be continued up to 2 times(600ms) in maximum. Therefore, please take a margin

for setting of timer such like 1 second.

Command value Command name Description of command send/receive

Data arrangement of the register to be sent from the master station to the remote register station. The command value should always be put in the first byte location of the register to be sent. Even if there is no data to be sent other than the command value, four words should be sent out as shown in the above. Therefore, always put 00H when there is no data.

Data arrangement of the register to be sent from the remote register station to the master station. When the master station sends a command, even if it is not a monitoring command of any kind, the remote register station will always send data back. When there is no data to send back, the remote register will give 00H. Always check data arrangement of the register shown above.

The bit configuration above represents the figure as shown in the right: . 10n

Value is expressed in a 3-digit decimal number. The decimal point is fixed for all values as

shown in the right: . (Example: When the ten bits above represents 356 (decimal number), it

will be read as 3.56.)

< Multiplier > The value above will be multiplied by 10n. In this calculation, the section n is

called a multiplier. The b14 represents + or - of the multiplier. b14=0 : 10+n , b14=1 : 10-n

< Polarity > b15=0 : The value is a positive number. b15=1 : The value is a negative number.

Regarding phase measurement, value data is equal to phase measurement. Multiplier and Polarity

have no meanings.[Example] In case of +10 deg.: 000AH, In case of 10 deg.: FFF6H, In case of

179 deg.: FF4DH.

Frequency, power factor and phase measurement are held at fixed value while ac voltage is gone

down to low level as an error of measurement data is bigger than the normal condition.

phase value. The polarity and the multiplier are disregarded.

[Example for] +10: For 000AH, -10: For FFF6H, -179:For FF4DH

However, when the input value of the voltage and the current is too small to be calculated,

10000(2710H) will be returned.

#2 Power factor

< Numerical value > follows the format of the above-mentioned, and the expression of leading power

factor and Lagging power factor is as follows. Leading power factor b15=0, Lagging power factor b15=1

When the input value of the voltage and the current is too small to be calculated, 1000(0864H) will be

returned.

Write the following command and related data in the remote register RWw, then switch the command execute request flag to 1 (ON). When the command end response flag becomes 1 (ON), this means that the remote register RWr has been received. Reading data of the register will obtain the waveform data. The waveform data monitoring command 89H should be used to set a monitoring range and read the initial 4-word data. This 8CH command should be issued when retrieving the following 4-word data or after. The master station will determine how many times to send data. Only the initial transmission will be made with the command 89H and the second and successive transmissions will be made with 8CH. Do not use the command 89H until the whole data of the target channel is read in. Please note that, if 8CH is sent without 89H setting, desired data can not be read.

Waveform data is accumulated by sampling every 30. As 30 sampling data is counted as one

point, one cycle (360) will be 12 points data. To retrieve waveform data, first issue the command

89H to specify a desired channel, phenomenon number, and data length (number of cycles) for

which you want to get data. Of the total data volume you specified, you will only obtain the leading

data of 4 points in the first stage. Next, send the command 8CH in turn to retrieve the following

4-point data. To obtain data for one cycle (12 points data). That is, you will first read the beginning

4-point data with 89H, then send 8CH twice to read the rest.

For instance, in the case you want to get data for 10 cycles spanning before and after a trip as

shown in the figure above (the red line shows the occurrence of trip), a 89H command should be

sent once (always first) and followed by 29 times of 89H command. Note that data of another

channel can not be read during data retrieval. For example, where you want to read 10-cycle data of

the channel #1, if you carry out another setting for the channel #2 at the time when you have just

read data for only 3 cycles of the channel #1, data that can be read with 8CH will be limited to the

channel #2 data. In other words, the command 8CH will only allow reading data of the channel

specified with the 89H. If 8CH data is sent without 89H setting, desired data can not be obtained.

When reading waveform data, always specify data with the command 89H before using 8CH.

5.2 Switch setting

(1) Setting baud rate

The setting switch indicated in the previous section is used to set the baud rate. The numbers 0

to 4 are allowed in setting. Setting any other number will cause an error. Error will also occur

when you try to change the setting under normal operation.

The baud rate set here must be identical to the baud rate set in the master station.

(2) Setting channel number

The setting switches indicated in the previous section are used in combination to set the channel

number. When a combination of the one and ten places represents 0 or over 65, an error

should occur. Error will also occur when you try to change the setting under normal operation.

For more information about this setting, see the master unit user manual.

Caution: The switches (S4) mounted on the back of the channel number (the ten place) setting

switch should be all set in the OFF positions.
