Modbus operations
Read approved registers and permit writes only when the lease policy explicitly allows them.
Industrial OT access
Remote maintenance with clear operating boundaries
Give engineers temporary access to the exact industrial resource they need, limit what they can change, and preserve the record of every approved operation.
What you can do
Built around the job, not the jargon
OPC UA access
Read or update approved nodes while enforcing an exact allowlist for sensitive operations.
Industrial Ethernet identity
Identify supported networked controllers before deeper work begins.
Maintenance windows
Limit selected capabilities to the working hours configured for a team and timezone.
Emergency stop
An authorized operator can immediately revoke the lease, close access, restore availability, and record the reason.
Exact-resource authorization
A reservation for one controller cannot be reused to operate another controller by changing an identifier.
A clear workflow
From invitation to completed work
- 1
Define the boundary
Choose the equipment, time window, and permitted reads, writes, registers, or nodes.
- 2
Approve access
Issue the reservation directly or require a second authorized approver.
- 3
Operate and audit
Execute permitted work, stop immediately if needed, and retain a clear record.
Common questions
Good to know
Can a read-only session write to a controller?
No. Write operations are blocked unless the active lease explicitly allows them.
Can access be limited to selected Modbus registers?
Yes. A lease can define an allowed register range.
Is there an emergency stop?
Yes. Authorized operators can revoke a live industrial lease immediately and record the reason.
