first start. The actual value of the OK, or batch, counter is reset when a "Select Parameter set" message
(MID 0018) is received from Open Protocol but is unaffected by Enable/Disable commands.
Allow Client control specifies how control messages (see below for a listing which these are) from the
Open Protocol client should be treated by the tightening controller. Choose one of the following
alternatives:

Always : Select this alternative if control messages should be accepted regardless if the station is
in Automatic or Manual mode.

In Automatic mode : (Default). Select this alternative if control messages only should be accepted
when the station PLC output MODE is equal to zero.

Never : Select this alternative if control messages never should be accepted.
See Automatic/manual mode for a description on the differences between Automatic and Manual mode.
The following messages from the Open Protocol client are regarded as control messages:

MID 0018, "Select Parameter set"

MID 0042, "Disable tool"

MID 0043, "Enable tool "

MID 0050, "Vehicle Id Number download request"
When these are received in a state when they are not wanted according to the value of the Allow Client
control
parameter PowerMACS will respond with a “Command Error" (MID 0004) message with the field
"Error" set to 95 (Reject request, PowerMACS is in manual mode).
Station Controller specifies if this device is allowed to read/write user data to/from the PLC. If this is
checked the following messages from the Open Protocol Client are allowed.

MID 240, “User data download”

MID 241, “User data subscribe”

MID 242, “User data upload”

MID 243, “User data upload acknowledge”

MID 244, “User Data upload unsubscribe”
8.11.1.1 Automatic/manual mode
The station controlled by the Open Protocol device is always in either Manual or Automatic mode
depending on the current value of the PLC output MODE. If MODE is zero the station is in Automatic
mode and if it is non-zero the station is in Manual mode.
The following messages can be used by Open Protocol to supervise the stations with respect to its
Manual/Automatic state:

MID 0400, “Automatic/Manual mode subscribe”
