5. Site Service

Access via client.site(). A site (plant) is the top-level node of the asset hierarchy, and every OPC, Asset, Tag, and Order belongs to a site.

ID rule: The SITE_ prefix is required. See Domain ID Rules for details.

update(site_id, SiteRequestV5)	SiteResponseV5 or null	PUT	/api/v5/site/{id}
delete(site_id)	boolean	DELETE	/api/v5/site/{id}
get(site_id)	SiteResponseV5 or null	GET	/api/v5/site/{id}
list()	List<SiteResponseV5>	GET	/api/v5/site

5.4 Usage Examples

Creating a Site

import plantpulse.api.v5.dto.request.SiteRequestV5;
import plantpulse.api.v5.dto.response.SiteResponseV5;

SiteRequestV5 req = new SiteRequestV5();
req.setSite_id("SITE_DJ");
req.setSite_name("대전 1공장");
req.setDescription("주력 생산 공장");
req.setLat("36.3504");
req.setLng("127.3845");

SiteResponseV5 created = client.site().create(req);
if (created != null) {
    System.out.println("등록 완료: " + created.getSite_id());
}

Retrieving a Single Site

SiteResponseV5 site = client.site().get("SITE_DJ");
if (site != null) {
    System.out.println(site.getSite_name());
    System.out.println("Area 수: " + site.getTotal_area_count());
    System.out.println("Line 수: " + site.getTotal_line_count());
    System.out.println("Equipment 수: " + site.getTotal_equipment_count());
    System.out.println("Tag 수: " + site.getTotal_tag_count());
}

Full List

import java.util.List;

List<SiteResponseV5> sites = client.site().list();
for (SiteResponseV5 s : sites) {
    System.out.println(s.getSite_id() + " — " + s.getSite_name());
}

Updating a Site

SiteRequestV5 update = new SiteRequestV5();
update.setSite_id("SITE_DJ");                // 동일하게 채워서 보내야 합니다
update.setSite_name("대전 1공장 (확장)");
update.setDescription("2026년 라인 증설 완료");

SiteResponseV5 updated = client.site().update("SITE_DJ", update);

Checking Existence

if (client.site().exists("SITE_DJ")) {
    // ...
}

Deleting a Site

⚠️ Before deleting a site, you must first delete every Asset, OPC, Tag, and Order belonging to it. Otherwise you will receive a E1200 (CONFLICT) response and false is returned.

boolean ok = client.site().delete("SITE_OLD");
if (!ok) {
    System.err.println("삭제 실패 — 하위 리소스 존재 가능");
}

5.5 Application Scenarios

Scenario — Per-Site KPI Dashboard

for (SiteResponseV5 site : client.site().list()) {
    String siteId = site.getSite_id();

    // 사이트별 자산 통계는 SiteResponseV5에 이미 포함됨
    int eqCount  = site.getTotal_equipment_count();
    int tagCount = site.getTotal_tag_count();

    // 사이트별 OPC 수
    long opcCount = client.opc().countBySite(siteId);

    System.out.printf("%s — Equipment %d, Tag %d, OPC %d%n",
        site.getSite_name(), eqCount, tagCount, opcCount);
}
