• RWS XHTML v2.0 profile enabled
• HTTPS connection (example: https://127.0.0.1:55 or robot IP)
• Valid credentials (Digest or Local login)

Key Variables

Variable	Example	Description
baseUrl	https://127.0.0.1:55	Controller base URL
username	robot	Username
password	robot	Password
task	T_ROB1	Main RAPID task
module	MainModule	RAPID module name
signal	DO1	Target IO signal
domain	rapid	Mastership domain
ccount	0	Motion system change count
resources	/rw/iosystem/signals/Local/0/DO1;state	Example subscription resource

---

How to Import

1. Open Postman
2. Click Import → File
3. Set environment variables:

• baseUrl = https://127.0.0.1:55
• username / password according to your setup

5. Run a simple test:
   GET {{baseUrl}}/rw → should return the RW index.

---

Authentication

• Type: HTTP Digest (or Local depending on configuration)
• Some operations (IO, RAPID, Motion) require RMMP Modify or Mastership privileges.

Example sequence:

1. POST /users?action=set-local
2. POST /users/rmmp?action=request
3. POST /rw/mastership?action=request&domain=rapid
4. Then execute your RAPID or IO commands

---

🧠 Tips & Troubleshooting

• 406 Not Acceptable: ensure
  Accept: application/xhtml+xml;v=2.0
• 404 Not Found: verify your baseUrl and that the controller is in Auto mode with motors ON.
• Jog flow example:

1. Read /rw/motionsystem?resource=change-count
2. Execute POST /rw/motionsystem?action=jog using the same ccount.
