id is provided it must be accepted if the function code is set to force accept or clear force accept with force a message with a function code of normal id will be subject to potential discard via the message id validation rules if gateway 18 has reset it should make its first request using the force accept function code the will force the receiving field device to accept the request and the attached message id this relieves gateway 18 of needing to learn the value of the device 39 s valid message id counter gateway 18 should stop using force accept once it has received a valid response message with the matching message id gateway 18 should honor the clear force accept with force function code as a valid message id but a wdr field device should not send clear force accept with force to gateway 18 if a wdr field device in the system has reset it should send publish messages with the command set to force accept this will force gateway 18 to accept the published data if gateway 18 sees the force accept function code it may issue a clear force accept with force in a subsequent message along with a valid message id on receipt of clear force accept with force the wdr field device should clear the force accept condition and always accept the message id provided the use of embedded control messages in a control message protocol within wireless messages in a wireless protocol enables the host computer of a distributed control system to interact with field devices through a wireless communication network control messages can.
