Telecontrol equipment and systems -- Part 5-101: Transmission protocols - Companion standard for basic telecontrol tasks

This part of IEC 60870-5 applies to telecontrol equipment and systems with coded bit serial
data transmission for monitoring and controlling geographically widespread processes. It
defines a telecontrol companion standard that enables interoperability among compatible
telecontrol equipment. The defined telecontrol companion standard utilizes standards of the
IEC 60870-5 series of documents. The specifications of this standard present a functional
profile for basic telecontrol tasks. Further companion standards, based on the IEC 60870-5
series are under consideration.
This standard defines ASDUs with time tags CP24Time2a which includes three octets binary
time from milliseconds to minutes. In addition to these specifications, ASDUs with time tags
CP56Time2a, which includes seven octets binary time from milliseconds to years, are defined
in this standard (see 6.8 of IEC 60870-5-4 and 7.2.6.18 of this standard).
ASDUs with time tags CP56Time2a are used when the controlling station is not able to add the
time from hours to years unambiguously to the received ASDUs which are tagged from
milliseconds to minutes. This may happen when using networks with uncertain transmission
delays or if temporary failure of a network occurs.
Although this companion standard defines the most important user functions, other than the
actual communication functions, it cannot guarantee complete compatibility and interoperability
between equipment of different vendors. An additional mutual agreement is normally required
between concerned parties regarding the methods of use of the defined communication
functions, taking into account the operation of the entire telecontrol equipment.
Standards specified in this standard are compatible with standards defined in IEC 60870-5-1 to
IEC 60870-5-5 (see Clause 2).

Cette norme existe seulement en langue anglaise.

Oprema in sistemi za daljinsko vodenje - 6-101. del: Protokoli prenosa - Spremljevalni standardi za osnovne naloge daljinskega vodenja (IEC 60870-5-101:2003)

Ta del standarda IEC 60870-5 velja za opremo in sisteme za daljinsko vodenje s serijskim prenosom kodiranih bitnih podatkov za spremljanje in nadzor geografsko razširjenih procesov. Opredeljuje spremljevalni standard za daljinsko vodenje, ki omogoča interoperabilnost med združljivo opremo za daljinsko vodenje. Obravnavani spremljevalni standard uporablja standarde iz skupine dokumentov standarda IEC 60870-5. Specifikacije tega standarda predstavljajo funkcionalni profil za osnovna opravila daljinskega vodenja. Nadaljnji spremljevalni standardi, ki temeljijo na skupini dokumentov standarda IEC 60870-5, so še v obravnavi.
Ta standard določa podatkovne enote aplikacijskih storitev (ASDU) s časovnimi označevalniki CP24Time2a, ki vključujejo trioktetni dvojiški zapis časa od milisekund do minut. Poleg teh specifikacij so v tem standardu (glej točko 6.8 standarda IEC 60870-5-4 in točko 7.2.6.18 tega standarda) opredeljene podatkovne enote aplikacijskih storitev s časovnimi označevalniki CP56Time2a, ki vključujejo sedemoktetni dvojiški zapis časa od milisekund do let. Podatkovne enote aplikacijskih storitev s časovnimi označevalniki CP56Time2a se uporabljajo, kadar v nadzorni postaji prejetim podatkovnim enotam aplikacijskih storitev, ki so označene z zapisom časa od milisekund do minut, ni mogoče nedvoumno dodati zapisa časa od ur do let. Do tega lahko pride ob uporabi omrežij z negotovimi zamudami pri prenosu ali če pride do začasne okvare omrežja.
Čeprav poleg dejanskih komunikacijskih funkcij ta spremljevalni standard določa najpomembnejše uporabniške funkcije, ne more zagotavljati popolne združljivosti in interoperabilnosti med opremo različnih proizvajalcev. Običajno je potreben dodaten vzajemni sporazum med zadevnimi strankami glede metod uporabe določenih komunikacijskih funkcij, pri čemer je treba upoštevati delovanje celotne opreme za daljinsko vodenje. Standardi, določeni v tem standardu, so združljivi s standardi, določenimi v standardih od IEC 60870-5-1 do IEC 60870-5-5 (glej točko 2).
