A one-metre flexible link for one permitted break in the S7-200 SMART expansion chain.
Siemens 6ES7288-6EC01-0AA0 is a 1 m SIMATIC S7-200 SMART I/O expansion cable for separating adjacent units in a supported CPU and expansion-module chain. It carries the expansion connection across a cabinet layout where direct side-by-side module engagement is not practical.
A system can use one Siemens 6ES7288-6EC01-0AA0 either between the CPU and first expansion module or between two expansion modules. The cable does not create another expansion segment or increase the controller's module allowance; it only relocates one part of the existing chain.
Mechanical support matters for Siemens 6ES7288-6EC01-0AA0 because the 1 m assembly weighs 80 g and must not hang from the module connectors. In panels exposed to vibration, strain relief and routing support keep connector load away from the CPU and I/O housings.

Power down the CPU and compare the installed module sequence with the hardware project before fitting Siemens 6ES7288-6EC01-0AA0. Select one point after the CPU or between expansion modules, confirm that only one expansion cable is used, and leave enough space for the cable bend without pressing on adjacent terminals.
Seat both ends of Siemens 6ES7288-6EC01-0AA0 in the matching expansion connectors and secure the separated module group on its rail. Do not form a star connection, reverse the module order or allow the cable to carry the weight of the remote assembly.
Route Siemens 6ES7288-6EC01-0AA0 away from sharp edges, moving cabinet hardware and power conductors that can impose mechanical or electrical stress. Add strain relief near each module group, then inspect connector seating again after the cable is dressed.
Keep every module before and after Siemens 6ES7288-6EC01-0AA0 in the same physical order shown in the S7-200 SMART hardware configuration. Address changes caused by swapping modules can make the remote group appear connected while program signals point to the wrong channels.
Adding Siemens 6ES7288-6EC01-0AA0 changes distance, not CPU resources. Recheck the supported expansion-module count and available system power for the entire chain; the cable must not be used to justify an extra module or an uncalculated load.
After restoring power, use the CPU and module diagnostics to walk through the chain containing Siemens 6ES7288-6EC01-0AA0 from the first local module to the last remote module. Verify expected I/O at each position so a connector or sequence fault is located before production starts.
Power down and inspect both connectors of Siemens 6ES7288-6EC01-0AA0, the cable orientation and the first module after the cable. Then compare the physical module order with the project because one open link removes every downstream module.
The supported arrangement permits one Siemens 6ES7288-6EC01-0AA0 per CPU system. Do not create a longer or multi-break backplane path by cascading two cables.
Siemens 6ES7288-6EC01-0AA0 may link the CPU to the first expansion module or connect two adjacent expansion modules. It remains part of one continuous ordered chain.
If Siemens 6ES7288-6EC01-0AA0 is unsupported, cable movement and its 80 g mass can load the connectors. Add strain relief, eliminate tension and inspect connector seating before suspecting the I/O electronics.
No. Siemens 6ES7288-6EC01-0AA0 changes physical spacing only; the CPU's module count, bus-current budget and configured hardware order still apply.
Keep Siemens 6ES7288-6EC01-0AA0 away from sharp bends and moving hardware, preserve connector access and maintain the exact downstream module order. Recheck the complete chain after the cabinet is secured.
