10.5.6 Servicing of Analog Outputs
In the case of fitting the optional piggyback OT-13 or OT-14, the sw con-
figuration of BM standard-fitted inputs and outputs is complemented in the
way which depends on the BM type.
In BM of TC601 to TC604, the sw configuration is complemented by the
new directive
#unit
for the
piggyback OT-13 or OT-14. Example of the di-
rective:
#unit 0, 0, Analog_600_, 0, 4, 0, Yn, On
; analog outputs of OT-13
#unit 0, 0, Analog_600_, 0, 8, 0, Yn, On
; analog outputs of OT-14
Placement of image of outputs (parameter Yn) depends on the BM type
(is linked to image of binary outputs).
In BM of TC605 and TC606, the directive
#unit
of analog inputs and
outputs is complemented by parameters for the piggyback OT-13 or OT-14.
Examples of the extended directive:
#unit 0, 0, Analog_600_, 8, 4, X2, Yn, On, IniAI
; analog inputs of BM
; and analog outputs of OT-13
#unit 0, 0, Analog_600_, 8, 8, X2, Yn, On, IniAI
; analog inputs of BM
; and analog outputs of OT-14
Placement of image of outputs (parameter Yn) depends on the BM type
(is linked to the image of binary outputs).
BM analog outputs occupy 4 or 8 bytes in the image of outputs in the
scratchpad, depending on the type of the fitted piggyback (parameter of the
directive
#unit POC_OUT = 4 or 8
). Setting of the outputs according to
the binary representation of levels written in images of outputs is done in the
cycle loop. Initial address of the zone in the scratchpad is defined by the pa-
rameter
Z_OUT
of directive
#unit
Zone of images of analog outputs in the scratchpad has the following
structure:
AO0 .7
.6
.5
.4
.3
.2
.1
.0
Z_0UT
AO1 .7

Z_OUT+1

AO7 .7

Z_OUT+7
Besides the way of outputs control given above, analog outputs are ac-
cessible by direct writing of instructions WR with the operand U and the
physical output address. For structure of the physical address see item
10.5.12.
10.5.7 Servicing of Serial Channels
Declaration of CH1 is not performed.
CH2 is assigned to the scratchpad memory by the directive
#unit
with
general structure according to 10.5.2.
CH3 is declared in the case that the optional piggyback MR-14 or MR-15
is fitted, and in the same way as CH2.
Automatically generated sw configuration contains the directive
#unit
for CH2 and CH3 only after previous writing of the directive by the user.
#unit 0, 2, _CHx, 255, 255, R0, R255, On, IniCH2
; serial channel CH2
#unit 0, 3, _CHx, 255, 255, R510, R764, On, IniCH3
; serial channel CH3
