Possible errors bits are 0 and 3. See Request Error Bits, N12:5,13,21.. (page 16)
Bit 5 (0020)
(x_RGETREG)
Request register contents. The numerical value of the register number must be
present in the MC Request Integer Parameter N13:5,12,19.. (page 18). Upon
completion, bit 5 of Request Done Bits, N12:4,12,20.. (page 16), will be set. If
no errors occurred, the content of (value in) the register will be present in
Request Float Result F14:6,14,22.. (page 19). Possible errors bits are 0 and 2.
See Request Error Bits, N12:5,13,21.. (page 16).
Note. An easier and more efficient method of getting the content of a MC
register is to tag it. See Fast Tag Register Number, N13:0,7,14.. (page 17) and
Slow Tag Register Number 1 - 3 N,13:1-3,8-10,15-17.. (page 17)
Bit 6 (0040)
(x_RPUTREG)
Update register contents. The numerical value of the register number to
update must be present in the MC Request Integer Parameter N13:5,12,19..
(page 18). The numerical value of new register content must be present in MC
Request Float Parameter, F15:1,4,7.. (page 19) Upon completion, bit 6 of the
Request Done Bits, N12:4,12,20.. (page 16), will be set. Possible errors bits
are 0 and 2. See Request Error Bits, N12:5,13,21.. (page 16)
Bit 7 (0080)
(x_RCLRLRM)
Clear all general alarms or warnings. This has the same effect as pressing the
‘Clear General Alarms’ button on the MC² or the ‘ACK ALL’ touchpad on the
MC³. The MC General alarm or warning output will go to OFF state, and the
MC general alarm or warning indicator will go off. Note that Fault indicators,
existing in the MC³ models 30.10.EX and 24.10.EX will not be cleared, using
this request bit.
Bit 8 (0100)
(x_RCLRSUB)
Clear the subtotal. This has the same effect as pressing the ‘Clear Subtotal’
button on the MC. Possible error bit is 2. See Request Error Bits, N12:5,13,21..
(page 16)
Bit 9 (0200)
(x_RDLSEC)
Download secondary (batch) setpoints. This bit will cause any value (including
zero) in Secondary SetPoint, F15:2,5,8..(x_SECPT) (page 19) to be
continuously downloaded as a secondary (batch) setpoint to the MC.
Bit 10..15 Reserved
MC Request Integer Parameter N13:5,12,19..(x_RINTPAR)
This integer is used to hold request parameters. See MC Control Word, N13:4,11,18.. (page 17).
External Inputs, N13:6,13,20..
Logical inputs in some MC³ controllers can be mapped to up to 16 external inputs. They appear
as bits in this word. External input 1 corresponds to bit 0 etc. This is useful when the PLC
controls the MC inputs directly.
Floating Point Report File, F14
SuperBridge will maintain a PLC type floating point file, with 8 floats per connected MC. The
purpose of this file is to make floating point data available to the PLC ladder or MMI programmer.
The file is read only. The file name is F14.
The following is a specification of the 8 floats belonging to a certain MC.
